When heat is applied to a substance, it causes the molecules in the substance to gain energy and move faster, leading to an increase in temperature. This can result in phase changes, such as melting or boiling, depending on the substance. In chemical reactions, heat can also provide the activation energy needed for the reaction to occur.

What are the effect of heat on a substance?
Almost all the substance respond to heat. Heat is a type of energy which is more or less absorbed by almost all matters. The vital effect that heat causes is Expansion. Due to heat 3 types of expansion takes place within substances. They are: 1) Linear expansion of heat, 2) Surface expansion of heat & 3) Volumetric expansion of heat.
What does the specific heat of a substance represents?
The ability of a substance to hold heat.
How can one determine the heat of combustion for a given substance?
To determine the heat of combustion for a substance, one can conduct a calorimetry experiment where the substance is burned in a controlled environment and the heat released is measured. This heat release is then used to calculate the heat of combustion for the substance.
How do you calculate the heat of combustion for a given substance?
To calculate the heat of combustion for a substance, you can use the formula: Heat of combustion (mass of substance) x (heat capacity) x (change in temperature). This formula helps determine the amount of heat released when a substance undergoes complete combustion.
What will happen if non volatile substance is heated?
Heating a non-volatile substance will cause it to increase in temperature and potentially change its physical state (e.g. melting or sublimating) or undergo a chemical reaction. Once the heat source is removed, the substance will cool back down to its original state.
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
What happens if heat transfers through a graduated cylinder?
Well that depends, if you have substance within the cylinder, then the substance will begin to heat up due to the transfer of heat. But if you don't have anything within the cylinder then the cylinder will heat up on its own and might melt if you apply enough heat.
What are 2 reasons that a solution gets warmer when a new substance is added?
This is the effect of the heat of dissolution.
What is the effect of a substances density on its specific heat capacity?
The specific heat capacity of a substance is not directly affected by its density. Density refers to the mass of a substance per unit volume, while specific heat capacity is the amount of heat required to raise the temperature of a unit mass of the substance by one degree Celsius. The specific heat capacity of a substance is determined by its molecular structure and composition, not its density.
Can heat be trapped?
no, heat is not a substance, it is a form of energy.
What are the effect of heat on a substance?
Almost all the substance respond to heat. Heat is a type of energy which is more or less absorbed by almost all matters. The vital effect that heat causes is Expansion. Due to heat 3 types of expansion takes place within substances. They are: 1) Linear expansion of heat, 2) Surface expansion of heat & 3) Volumetric expansion of heat.
When you apply the same amount of heat 5 grams of water and 5 grams of the water the temperature of the limit increases more than the water what can you conclude?
If you apply the same amount of heat to 5 grams of water and 5 grams of another substance, and the temperature of the other substance increases more than that of the water, you can conclude that the other substance has a lower specific heat capacity than water. Specific heat capacity is the amount of heat required to raise the temperature of a substance, so a lower value means that it requires less energy to achieve the same temperature increase.
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 causes expanding gas to rise?
The reason why expanding gas rises is because of the heat that causes the molecules of the substance to move farther apart, making the substance occupy more space. The opposite effect is caused by a loss of heat.
What does the specific heat of a substance?
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.
What does the specific heat of substance represent?
The ability of a substance to hold heat.
