The more energetic substance will typically lose internal energy (i.e. "cool down") … WebThe heat transfer can be enhanced by increasing the mass flow rate of the system. For example : Suppose refrigerant is circulating through evaporator and condenser at specific mass flow rate X. Now, the requirement for cooling is increased. If we put the refrigerator at max, The mass flow rate of the refrigerant will get increase. WebOct 7, 2016 · The mass heat capacity (per unit mass) of a body, also called specific heat, is the body’s ability to store heat. This is precisely defined as the amount of heat required to raise the temperature of a 1kg mass by 1°C. As we have seen, it is 4.18 kJoules/kg/°C for liquid water (4.18 Joules per 1 g). This is a particularly high value. irs are gift cards taxable
