To calculate the heat lost by hot water in a system, you can use the formula Q mcT, where Q is the heat lost, m is the mass of the water, c is the specific heat capacity of water, and T is the change in temperature. This formula helps determine the amount of heat energy transferred from the hot water to the surroundings.
When allowed to stand for long enough, the final temperature will reach room temperature.
To calculate the heat capacity of a calorimeter containing water, you can use the formula Q mcT, where Q is the heat absorbed or released, m is the mass of water, c is the specific heat capacity of water, and T is the change in temperature. By measuring the temperature change when a known amount of heat is added or removed from the water in the calorimeter, you can determine the heat capacity of the calorimeter.
To calculate the heat of combustion for a substance, you can use the formula: Heat of combustion (mass of substance) x (heat capacity) x (change in temperature). This formula helps determine the amount of heat released when a substance undergoes complete combustion.
To lower the temperature of 53.0g of water from 65.0°C to 0°C, we need to calculate the heat required to cool the water and then use this heat to melt the ice. First, calculate the heat absorbed by the water using the formula: q = mcΔT, where q is the heat, m is the mass, c is the specific heat capacity of water, and ΔT is the temperature change. Then, use the heat absorbed to calculate the amount of ice melted using the heat of fusion of ice (334 J/g).
The enthalpy equation used to calculate the change in heat energy of a system at constant pressure is H q PV, where H is the change in enthalpy, q is the heat added or removed from the system, P is the pressure, and V is the change in volume.
The formula to calculate the natural convection heat transfer coefficient in a system is h k Gr(1/4) / L, where h is the heat transfer coefficient, k is the thermal conductivity of the fluid, Gr is the Grashof number, and L is the characteristic length of the system.
heat pumpEvery system that creates a chilled water, moves heat. An absorption system uses heat energy to remove heat from water and ice cream!.
When allowed to stand for long enough, the final temperature will reach room temperature.
A calorimeter uses the increase in water temperature to calculate the amount of heat transferred in a chemical reaction or physical process. By measuring the temperature change of the water, the calorimeter can determine the amount of heat absorbed or released by the reaction.
To calculate heat dissipation in a system, you can use the formula Q mcT, where Q is the heat energy, m is the mass of the object, c is the specific heat capacity of the material, and T is the change in temperature. This formula helps determine how much heat is being transferred and dissipated in the system.
The heat dissipation equation used to calculate the amount of heat transferred from a system to its surroundings is Q hAT, where Q represents the amount of heat transferred, h is the heat transfer coefficient, A is the surface area through which heat is transferred, and T is the temperature difference between the system and its surroundings.

there are no units given, so I assume your working in degrees c and joules?I'm afriad its not clear from the question what you want to know?You've said there is some water that is at -8c, and that it has a speicifc heat capacity of 2.04kj/kg-K after it has frozen? and that it gives up 332kJ/kg when it becomes a solid (ice)?
yes heat is given of due to the exothermic process in some cases. e.g when caco3 is mixed with water heat is given of.
