To calculate heat energy when you know volume and temperature, you would need to use the formula Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Given volume, you would also need to know the density of the substance to calculate the mass.
True. To calculate the energy released within a calorimeter, you need to know the volume of the substance, the temperature change, and the specific heat capacity of the substance (in this case, water). This information is necessary to apply the formula Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change.
The same as you would calculate for any other substance. You have to multiply all of the following: • The desired temperature difference. • The mass of the sample. • The specific heat, in this case, of coal.
The heat of fusion is used to first convert the volume of liquid to its solid form, then the heat of vaporization is used to convert the solid to vapor. By summing the two energy values, you can calculate the total energy required to vaporize the liquid volume.
The time required to heat a liquid depends on the initial temperature, desired final temperature, heat source power (in watts), and mass or volume of the liquid. The formula to calculate this time is: Time = (mass or volume) * specific heat capacity * change in temperature / heat source power.
You need the amount of water, the temperature of the water, and the desired temperature.

To calculate the volume of water boiled off, you need to know the initial volume of water, the heat input, the time it was heated, and the specific heat capacity of water. You can use the equation Q = mcΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Once you have the heat energy, you can convert it to volume using the density of water.

More heat energy is needed to raise the temperature of a larger volume of water because a larger volume of water contains more molecules, which require more energy to vibrate and increase their kinetic energy. This results in a greater heat capacity for the larger volume of water, meaning it can absorb more heat energy without a significant increase in temperature.

it doesn't it raises the average energy a particle has. that's temperature not heat.

With the relationships of temperature (Heat), pressure and volume an increase in temperature will increase the pressure and or the volume; a decrease in heat leads to a lower pressure or volume. Temperature is proportional to pressure. Temperature is inversely proportional to volume. In a chemical reaction an increase in heat drives the reaction to the extropy favoured side of the reaction. In Physics heat is a form of energy and can be converted into other forms of energy. In an motor the sum of the energies in (electromotive force in the form of electrical energy) equals the sum of the energies out (heat, emf, et cetera) In a generator heat can be used to make steam to generate electricity.

Specific heat is the measure of energy it takes to raise a unit mass in temperature by one degree Celsius. When measuring a compound that is water soluble, heat it separately to a specific range, then use the liquid to calculate the amount of heat that was used.
q( enthalpy of heat in Joules-energy ) = Mass of steel * heat capacity of steel * ( Temperature final - temperature initial )
