How does specific heat affect heat transfer
WebMar 26, 2024 · The basic effect of heat transfer is that the particles of one substance collide with the particles of another substance. The more energetic substance will typically lose internal energy (i.e. "cool down") … 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.

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. WebHeat is transferred from the soda to the ice for melting. Melting of ice occurs in two steps: first, the phase change occurs and solid (ice) transforms into liquid water at the melting temperature; then, the temperature of this water rises.
