The diagram shows the effect of solar energy on both land and sea on a hot, sunny day.

why is the air over the sea cooler even on a hot, sunny day?

question 5 options:

water has the ability to regulate its own temperature.

water keep flowing which prevents the water from heating up at all.

water needs to absorb a lot of solar energy to warm up.

water absorbs the sun's energy but does not transmit it.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
