Specific Heat & Calorimetry

Front

What is specific heat?

Back

The amount of energy required to raise the temperature of 1 kg of a substance by 1°C.

What happens to the temperature of a metal cube when it is placed in a liquid at a higher temperature?

Back

The temperature of the metal cube will increase until thermal equilibrium is achieved, resulting in a temperature between the initial temperatures of the cube and the liquid.

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of the particles in a substance.

Front

What is the purpose of insulating materials in calorimeters?

Back

To prevent heat from escaping to the environment, ensuring accurate measurements of heat transfer.

Front

If 4000 joules of energy is added to 100 mL of water and 1000 mL of water, which will have a greater change in temperature?

Back

100 mL of water will have a greater change in temperature because it has less mass to absorb the same amount of energy.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the formula for calculating heat energy (Q)?

Back

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

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is calorimetry?

Back

The science of measuring the heat of chemical reactions or physical changes.

Front

What is the unit of specific heat?

Back

The unit of specific heat is typically Joules per kilogram per degree Celsius (J/kg°C).
