Explain the concept of specific heat capacity in relation to thermal energy.

• Specific heat capacity is the measure of how much heat a substance can hold.

• Specific heat capacity is the rate at which a substance loses heat.

• Specific heat capacity is the ability of a substance to conduct electricity.

• Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by 1 degree Celsius.

Discuss the difference between conduction, convection, and radiation in relation to thermal energy transfer.

• Conduction is through material, convection is through fluids, and radiation is through electromagnetic waves.

• Conduction is through sound waves, convection is through light waves, and radiation is through heat waves.

• Conduction is through gases, convection is through solids, and radiation is through liquids.

• Conduction is through vacuum, convection is through vacuum, and radiation is through vacuum.

What is the formula to calculate thermal energy?

How does insulation play a role in conserving thermal energy?

• Insulation increases heat transfer, causing temperature fluctuations and reducing energy efficiency.

• Insulation has no impact on heat transfer or energy efficiency.

• Insulation reduces heat transfer, maintaining consistent temperature inside and improving energy efficiency.

• Insulation absorbs thermal energy, leading to overheating and energy waste.

Explain the concept of thermal equilibrium.

• Thermal equilibrium is the state where two objects in physical contact with each other have the same temperature.

• Thermal equilibrium is only applicable to solids.

• Thermal equilibrium is when objects have different temperatures.

• Thermal equilibrium occurs when objects are not in physical contact.
