c = Q / (m(change in temperature))
Where,
c = specific heat capacity
Q = amount of heat needed
m = mass
Change in temperature = initial temperature - temperature(after)
Take note that this equation cannot be used in calculating the change in state - melting and boiling
Because temperature do not change.
We therefore use:
Q = lv x m
Where,
lv = latent heat of vapourisation (for boiling/condensation ONLY)
m = mass
Q = lf x m
Where,
lf = latent heat of fusion (for melting/freezing ONLY)

How can calculate outlet temp of two fluids when inlet temp of two fluids are given?
You can calculate the outlet temperature of two fluids in a heat exchanger using the energy balance equation, which equates the heat gained by one fluid to the heat lost by the other fluid. By applying this equation along with the specific heat capacities and flow rates of the fluids, you can determine the outlet temperatures. Alternatively, software tools or online calculators can be used to simplify the calculation process.
How can the specific heat of water be used to determine the specific heat of an object?
If you know the temperature and mass of an object, and the temperature, mass, and specific heat of the water, if you dunk the object in the water, and measure the temperature of the water and the object (once the object and water have the same temperature), using reasoning skills and/or equations you can figure out the specific heat of the object. Historically the specific heat was related to SH of water . Water being 1 That now is seen as archaic. The specific heat (of a substance) is the amount of heat per unit mass required to raise the temperature by one degree Celsius. This does not apply if a phase change is encountered. Every substance has to be measured separately .
How do you find how much heat is gained in a specific heat problem?
To find the heat gained in a specific heat problem, you can use the formula: Q = mcΔT, where Q is the heat gained, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Simply plug in the values for mass, specific heat capacity, and temperature change to calculate the heat gained.

Is Calculate the Calorimeter Constant if 25 g of water at 56C was added to 25 g of water at 25C with a resulting temperature of 35C?
To calculate the calorimeter constant, you first need to use the formula for heat transfer: q=mcΔT, where q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Since the two water samples reached thermal equilibrium, the heat lost by the hot water is equal to the heat gained by the cold water. By rearranging the equation to find the calorimeter constant, you can solve for it using the given data.
