Thermal Energy & Waves

Conduction is the type of thermal energy transfer that can take place in solids, liquids, & gases when two objects are touching.

Radiation is the type of thermal energy transfer that can take place in gases only, as it does not require a medium for propagation.

Convection is the correct choice because it involves the transfer of thermal energy in fluids through the movement of warmer fluid rising and cooler fluid sinking, creating a current.

The thermal energy transfer shown in the image is radiation, as it involves the emission of heat energy in the form of electromagnetic waves.

The thermal energy transfer shown in the image is conduction, as it involves the direct transfer of heat through a material without any movement of the material itself.

The thermal energy transfer shown in the image involves the movement of heat through a fluid, which is characteristic of convection.

The heat would move from the water to the ice as the water is at a higher temperature (15°C) than the ice (0°C), causing the ice to melt and reach thermal equilibrium.

Heat transfer stops when both the coke and fridge reach the same temperature, which is 6 degrees in this case.

The correct choice is 'Energy cannot be created or destroyed' as it aligns with the Law of Conservation of Mass.

Specific Heat is the amount of energy required to raise the temperature 1ºC for every kilogram.
