Thermodynamics

What is specific heat?

• The amount of heat energy required to lower the temperature of a substance

• The amount of heat energy required to change the state of a substance

• Amount of heat energy required to raise the temperature of a substance

• The amount of heat energy required to break the bonds between atoms in a substance

Define calorimetry.

• The study of light and its properties.

• The science of measuring heat changes.

• The study of the Earth's atmosphere and weather patterns.

• The process of measuring electrical conductivity.

What is internal energy?

How is specific heat measured?

• By measuring the temperature change of a substance when heat is added.

• By calculating the mass of a substance and the change in temperature.

• By observing the color change of a substance when heat is applied.

• By determining the amount of heat required to raise the temperature of a substance by a certain amount.

What are the units of specific heat?

• J/m²

• J/m³

• J/°C

• J/kg°C or J/kgK

Explain the concept of calorimetry.

• Calorimetry is the measurement of pressure in a chemical or physical process.

• Calorimetry is the scientific measurement of heat transfer in a chemical or physical process.

• Calorimetry is the process of measuring the volume of a substance.

• Calorimetry is the study of light and its properties.

What is the formula to calculate internal energy?

• U = Q * W

• U = Q / W

• U = Q - W

• U = Q + W

What is the relationship between specific heat and temperature change?

• Specific heat is equal to temperature change.

• Specific heat has no relationship with temperature change.

• Specific heat is directly proportional to temperature change.

• Specific heat is inversely proportional to temperature change.

What are the units of specific heat?

• J/m²

• J/m³

• J/°C

• J/kg°C or J/kgK

What is the principle of calorimetry?

• The principle of calorimetry is the measurement of temperature in a system.

• The principle of calorimetry is the measurement of pressure in a system.

• The principle of calorimetry is the measurement of volume in a system.

• The principle of calorimetry is the measurement of heat transfer in a system.
