A substance gains heat, or otherwise known as thermal energy, in many different ways. These can be from pressure, friction, the transformation of chemical energy to thermal energy, the transformation of electromagnetic energy to thermal energy, potential energy to the energy of motion (kinetic energy) or a substance can become exothermic during, and after a chemical change if the amount of energy produced from the broken bonds is greater than the amount of energy required for rearranged bonds to be made.

What does the specific heat of a substance represents?
The ability of a substance to hold heat.
Substance A has a higher heat capacity than does substance B and substance B has a higher heat capacity than does substance C. If you add the same amount of heat to all three which order shows the pro?
c
What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
How do you use the word specific heat in a sentence?
The specific heat of a substance is the heat required to raise the temperature of one gram of the substance one degree centigrade.
What is name is given to a substance that does not let heat pass through it?
It i scalled insulator. The substance do not allow heat to pass through it It Is also heat resistant (dont let heat through it). An example of a heat resistant material is wood.
When a substance changes from a solid to a gas it needs to what energy?
gain heat energy.
How heat energy can change the states of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
If you were trying to find a substance that increases in temperature rapidly you should choose a substance with?
A substance with a low heat capacity.A substance with a low heat capacity.A substance with a low heat capacity.A substance with a low heat capacity.
What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What does the specific heat of a substance?
The ability of a substance to hold heat.
What does the specific heat of substance represent?
The ability of a substance to hold heat.
What does specific heat of a substance represent?
The ability of a substance to hold heat.
What does the specific heat of a substance represents?
The ability of a substance to hold heat.
How does the temperature of a substance change as it gains or loses heat?
A substance (in this case water) that gains or loses 'sensible' heat will change it's temperature at the rate of 1 deg F per pound of that substance per 1 btu loss or gain.That is to say that 1 pound of water will change 1 deg f as it loses or gains 1 btu of heat energy. That heat required to lose or gain 1 deg f is referred to as sensible heat, whether lost or gained, since it does change the temperature of the substance.However, that substance must gain or lose latent heat during a change of state; as in water changing from liquid to gas (steam). Latent heat affects the substance during it's change of state, and does not change the temperature of the substance during that change of state.Each substance has a specific heat, and so each substance has a different value of btu's required to make a change in their state or temperature.
Heat never of itself flows from a cold to a hot substance?
Heat can flow from cold to hot substances. It's flow depends on the total amount of heat of the substance not on the temperature. It flows from the substance which has more heat to the substance which has less heat stored in it.
How do you work out the quantity of heat?
by dividing the quantity of heat of a substance by the mass of that substance
Does melting lose or gain temperaturre?
loses When ice melts it gains heat. The environment, however, loses heat. So what does heat have to do with temperature? Often they vary in the same direction; temperature has been likened to the average kinetic energy of the substance. Melting typically ( e,g,, for ice-water) clamps the temperature at a constant value, but heat flows into the substance that melts.
