There are three methods by which substances absorb heat. These are conduction, or heat transfer through contact, convection, or heat transfer through fluid motion, and radiation, or heat transfer through electromagnetic radiation.

What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
Why the temperature does not rise during the process of melting and boiling though the heat energy is constantly supplied?
The energy must be applied to the phase change before it can heat the substance
How do water and land surfaces differ in their abilities to absorb and radiated heat energy?
Land absorbs more heat energy than water does.
Does geothermal energy change into another substance before it can create energy?
Geothermal energy is energy. It does not change into a substance, although it cam be transformed into other forms of energy. When it is not used directly to heat buildings, geothermal energy (heat) is typically used to run turbines for conversion to electrical energy
When writing a chemical reaction for an exothermic process will the heat energy be reactant or product?
Heat will be on the product side of the equation, but it is not a "product" in the same sense as the chemical symbol(s) and/or formula(s) written on this side of the equation, because heat is not a tangible substance but rather an increase in the energy of nearby substances.
How does temperature affect solubility of a substance which involves endothermic process in forming a solution?
endothermic substances absorb energy when dissolved. Therefore supplying energy(heat) externally will increase the solubility.
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
Why do endothermic reactions absorb heat?
a process or reaction in which the system absorbs energy from the surroundings in the form of heat.
Does melting lose or gain energy?
Generally, melting is the process of turning from a solid to a liquid. It entails gaining energy.
How does air absorb heat?
Air absorbs heat as does any other substance. The heat is absorbed into increasing kinetic energy of the particles that make up air.
The substance that would absorb the most heat energy with the least temperature change would be one kilogram of?
water
Explain why substances with hig specific heats take longer to heat up than substances wit the same mass which have low specific heats?
Type your answer here... A substance with high specific heat means it can absorb alot more heat energy before its temperature increases. A substance with low specific heat cannot absorb alot of heat energy so its temperature increases quickly because it cant absorb the heat. Remember there is a difference between Heat energy and Temperature. The ocean can absorb alot of heat energy but still feel like its cold in temperature. The tip of a needle can be at 1000 degrees temperature but there is hardly any actual heat energy in it because its so small.
What does a substance absorb when it melts or boils?
Heat
What substance would absorb the most heat energy with the least change in temperature water or copper?
By far it is water.
Do black objects absorb heat?
They absorb light which is converted into heat energy
