Hi I really need help 7th grade science Water gets soaked up by a paper towel because of the property of blank Adhesion Cohesion Deposition Evaporation
Answer:
Adhesion
Explanation:
Water is soaked up by a paper towel because the forces of adhesion exceeds the forces of cohesion.
The forces of adhesion binds the water molecule to the paper towel while the forces of cohesion binds the water molecules to each other.
Adhesion of water to the walls of the paper exerts an upward force that draws water molecules up the paper.
Hence, the movement of water up a paper towel occurs when the forces of adhesion to the walls of the paper is greater than the forces of cohesion acting between the water molecules.

What is an element?Element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.Each element has its own characteristic property.

A can was filled with crushed ice, sealed, and massed. The ice was melted by slowly warming the can and its contents. No water vapor escaped and no air entered the can. If the can is then massed again after the ice has melted, what is the best prediction of the mass?
A) The mass would be the same.
B) The mass would be more.
C) The mass would be less.
D) It is impossible to predict without more information.
Answer:
A) The mass would be the same.
Explanation:
Since there is no loss of any particle to vapor during the phase change process from solid to liquid, the mass of the before and after the process will remain the same.
In this way, the law of conservation of mass is obeyed. Mass is the amount of matter contained in a substance. Since there is no room for escape or matter loss, the mass will remain the same.Answer:

An object has a mass of 60 ounces and a volume of 30 cups. What is the density? _______ oz/cup (your answer should *only* be a number, round to one decimal place if needed) *
Answer:
2.0
Explanation:
Given data:
Mass of object = 60 ounce
Volume of object = 30 cups
Density = ?
Solution:
d = mass/ volume
d = 60 ounce/ 30 cup
d = 2.0 oz/cup
Thus, density of object is 2.0 oz/cup.

The statement which best describes the change in the energy and physical characteristics of the molecules of carbon dioxide during this process is (B) The molecules experienced a chemical change as the carbon dioxide reacted with oxygen, which released oxygen gas into the environment and increased the molecular movement.Hence, The correct option is (B)
What is Physical Change ?Physical changes are those that affect a chemical substance's form but not its chemical content.
Physical changes may normally be used to separate compounds into chemical elements or simpler compounds, but they cannot be used to separate mixtures into their component compounds.
A change in physical attributes accompanies a physical change. Melting, turning into a gas, and changing strength are a few examples of physical qualities.
Therefore, molecules of carbon dioxide during this process is (B) The molecules experienced a chemical change as the carbon dioxide reacted with oxygen, which released oxygen gas into the environment and increased the molecular movement.Hence, The correct option is (B)

Answer #1: Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth's internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.
Answer #2:Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Subduction zones are sites that usually have a high rate of volcanism and earthquakes.

Which of the following correctly shows the flow of energy in a food chain
The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers, than finally after death of an organism, to decomposers
The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.
What is food chain?The sequence of events within an ecosystem known as a "food chain" occurs when one live organism eats a different organism, which is then eaten by a larger organism. A food chain is created by the transfer of energy as well as nutrients from one creature to another at various trophic levels. A food web is comprised of numerous linked food chains.
The feeding habits or connections between living things are also explained by the food chain. Trophic level is the term used to describe the orderly phases in a food chain, from producers from the bottom through primary, secondary, and tertiary consumers. A trophic level is any position along a food chain. A food web and a food chain are similar, but a food web seems far bigger. The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.
Therefore, the direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.
