Answer:

Convection occurs when thermal energy is transferred by the movement of fluids.

Explanation:

Convection is one of the three forms of heat transfer (conduction, convection and radiation) that transports heat between zones with different temperatures. Convection itself is the transport of heat through the movement of fluid. For example, when heating water in a saucepan, the water in contact with the base of the pan rises, while the water from the surface descends and occupies the place left by the hot one.

Answer:

Convection occurs when thermal energy is transferred by the movement of fluid particles.

Explanation:

Transfer of heat energy by the movement of fluid particles is called convection. Convection takes place in liquids and gases due to kinetic energy. When heat is provided to liquids and gases they expand and move faster.

Molecules with higher kinetic energy become less dense and rise up to the surface of liquid, whereas molecules with lower energy move towards the bottom. This up and down movement of molecules causes convection currents in fluids.

yKpoI14uk [10]

Answer:

11760 joules

Explanation:

Given

Mass (m) = 75kg

Height (h) = 16m

Required

Determine the increment in potential energy (PE)

This is calculated as thus:

PE = mgh

Where g = 9.8m/s²

Substitute values for m, g and h.

P.E = 75 * 9.8 * 16

P.E = 11760 joules
