Answer:
The pressure increases
Explanation:
In this action it is best to apply Boyle's law to resolve the problem. This is an interplay between Volume, Pressure and Temperature.
According to Boyle's Law "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant". Since the volume is being reduced to cram into the container, the pressure of the gases increases. In the smaller container, pressure rises and the volume reduces if temperature remains constant.Ice floats due to its?
Answer: it floats because it’s less dense than water
Explanation: since it’s less dense it floats
An exacuted glass vessel weighs 50 g when empty, 148g when filled with an liquid of density o.989/cc and 50.5 g whenfilled with an ideal gas760 mmHg and at 300k. Determine the molecular weights of gss.
MW of gas : 124.12 g/mol
Further explanationDensity is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
glass vessel wieight = 50 g
glass vessel + liquid = 148 ⇒ liquid = 148 - 50 =98 g
volume of glass vessel :
[tex]\tt V=\dfrac{m}{\rho}=\dfrac{98}{0.989}=99.1~ml[/tex]
An ideal gas :
m = 50.5 - 50 = 0.5 g
P = 760 mmHg = 1 atm
T = 300 K
[tex]\tt PV=\dfrac{mass(m)}{MW}.RT\\\\MW=\dfrac{m.RT}{PV}\\\\Mw=\dfrac{0.5\times 0.082\times 300}{1\times 0.0991}=124.12~g/mol[/tex]

_____________________________________CALORIMETER:Calorimeter is device used for the measurement of heat. In a calorimeter we can use the temperature change of water to quantify an amount of heat. A calorimeter just captures all the energy released (or absorbed) by a reaction in the water. So Option A and B are wrong as calorimeter don't have anything to do with providing the heat or letting the the heat in, as it is the insulated calorimeter too.
_____________________________________Energy in the reaction:In the formation of any bond there is equal amount of heat required as to break that bond. It means Energy released in the making of bond is equal to the energy required in the breaking of the bond. So Option D is wrong as it says we need more energy in making then breaking.
_____________________________________Enthalpy:Enthalpy is the total heat content of the system. As we provide energy to the reactants and the product is formed, so The enthalpy(heat content) of product is more than the Enthalpy of the reactant, Thus Option C is correct.
Enthalpy is denoted by H or Q, its formula is,
H = U + PV
Where,
U is internal energy
PV is equals to Work done ; P = Pressure, V = Volume

How can the gravitational potential energy of an object be changed?
Answer:
Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force will do an amount of work equal to mgh on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).

what are the similarities and differences between the crocodile , sheep , and gorilla digestive system?
Answer: Crocodile is a reptile whereas sheep and gorilla are the mammals.
Explanation:
Crocodile, sheep, and gorilla have alimentary canal in their digestive system. The urea is the common excretory waste.
Mouth is typically large in case of crocodile and comparatively small in sheep and gorilla.
In crocodile more sharp teeth are present as compared to sheep and gorilla for mastication of food and capturing the prey like fish or large animals like zebra.
The crocodile palate is more stronger than sheep and gorilla because it enable it to chew the bones of the prey.

A photon has an energy of 2.34x10-28 J. What is its frequency?
Answer:
f = 3.53×10⁵ s⁻¹
Explanation:
Given data:
Energy of photon = 2.34×10⁻²⁸ J
Frequency = ?
Solution:
h = 6.63 ×10⁻³⁴
Formula:
E = hf
2.34×10⁻²⁸ J = 6.63 ×10⁻³⁴ × f
f = 2.34×10⁻²⁸ J / 6.63 ×10⁻³⁴ Js
f = 0.353×10⁶ s⁻¹
f = 3.53×10⁵ s⁻¹

Answer:
Gas pressure is caused when gas particles hit the wall of their contains. the more often the particles hit the walls, and the faster they are moving when they do this , the higher the pressure .
Explanation:
When 50.0 mL of 1.000 M HCl is reacted with 50.0 mL of 1.000 M NH4OH, the solution's temperature increases 8.65 °C. Calculate qsolution in units of kJ. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL.
Answer:
Explanation:
Total volume of solution = 100 mL .
Total mass of the solution = 100 x 1.01 g
= 101 g
specific heat of solution = 4.184 J/g-°C
rise in temperature = 8.65 °C
heat released = mass x specific heat x rise in temperature
= 101 x 4.184 x 8.65
= 3655.35 J
= 3.655 kJ .
qsolution = 3.655 kJ .

Amorphous solids have two characteristic properties. When cleaved or broken, they produce fragments with irregular, often curved surfaces; and they have poorly defined patterns when exposed to x-rays because their components are not arranged in a regular array. An amorphous, translucent solid is called a glass

What is an atom?
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
