Heat and Calorimetry

Front

What is heat?

Back

Heat is a form of energy that is transferred between systems or objects with different temperatures (from hot to cold).

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

What is the formula for calculating heat transfer?

Back

q = mcΔT, where q is the heat added, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Front

What is calorimetry?

Back

Calorimetry is the science of measuring the heat of chemical reactions or physical changes.

Front

What is the specific heat capacity of water?

Back

4.184 J/g°C.

Front

How does mass affect temperature change when heat is added?

Back

The greater the mass of a substance, the smaller the temperature change for a given amount of heat added.

Front

What happens when two substances at different temperatures are mixed?

Back

Heat will flow from the hotter substance to the cooler one until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is the relationship between heat and temperature change?

Back

Heat added to a substance results in a temperature change, which is proportional to the mass and specific heat capacity of the substance.
