Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Q3/Answer by true or false : 1) All water systems using fan coil units are suitable in buildings requiring individual room control and consume less space compared to all air systems. 2) All air conditioning systems make use of an economizer. 3) With 100 % re-circulated air, some time, the room ADP is equal to coil ADP and the load on the coil is equal to the load on the room. 4) The sensible load affects dry bulb temperature, while the latent load affects the moisture content of the conditioned space. 5) A single zone, single duct, constant volume system can be used either for cooling or for heating, but not for both cooling and heating simultaneously.

I need answers with clear hand writing or using Microsoft word . ASAP informations of thermal system
select if true or false for the following questions 1. For a standard condenser in a refrigeration system, the thermal energy (in J) is equal to the mass (in kg) multiplied by the change in enthalpy across the condenser (in J/kg). 2. Consider a basic refrigeration cycle: Since it requires less work to compress a liquid than a vapor, the entire refrigeration process would work better if the compressor was replaced with a pump. All else being equal, increasing the mass-flow rate of refrigerant will increase the rate of heat transfer at the system’s evaporator. All of these (except, of course, the one labeled, “None of these.”) None of these.
