When calculating heat transfer, how would one know when to use Q=T*m*(delta s) versus Q=m*(delta h). I'm confused when we should calculate using entropy versus enthalpy. Anything helps. Thank you!
Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference between them. It can occur through conduction, convection, or radiation.
Heat transfer can be calculated using the formula Q = mcΔT, where Q is the amount of heat transferred, m is the mass of the object, c is the specific heat capacity, and ΔT is the change in temperature.
Conduction is the transfer of heat through direct contact between two objects. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves.
Heat transfer can cause a change in temperature by either increasing or decreasing it. When heat is transferred to an object, its temperature increases. When heat is transferred away from an object, its temperature decreases.
The rate of heat transfer is affected by several factors, including the temperature difference between the objects, the thermal conductivity of the materials, the surface area of contact, and the distance between the objects.
