To calculate superheat, subtract the actual temperature of the refrigerant from its saturation temperature at the current pressure. This will give you the superheat value, indicating how much the refrigerant has increased in temperature above its saturation point. Superheat is important in ensuring optimal functioning of air conditioning and refrigeration systems.

How do you calculate the output of a gas fire?
To calculate the output of a gas fire, you need to know the heat input rating of the gas fire in British thermal units per hour (BTU/hr) or kilowatts (kW). The heat output is typically a percentage of the heat input, commonly around 70-90%. You can calculate the heat output by multiplying the heat input by the efficiency percentage (e.g. heat output = heat input x efficiency percentage).
How many grams of ice at -12.1 can be completely converted to liquid at 14.7 if the available heat for this process is 4390?
To calculate the heat required to convert ice to liquid at a temperature of 14.7°C, we first need to heat the ice from -12.1°C to 0°C, using the specific heat capacity of ice. Then we calculate the heat required to melt the ice at 0°C to water at 0°C, using the heat of fusion of ice. Finally, we calculate the heat required to heat the water from 0°C to 14.7°C, using the specific heat capacity of water. By performing these calculations, we can determine if the available heat of 4390 J is sufficient.
Are specific heat and heat of fusion the same thing?
No. Specific heat capacity (c) is used in to calculate energy when matter is not undergoing a phase change [Q = mc(delta)T]. Heat of fusion (HF) is used to calculate energy when matter is either melting or freezing [Q = m(HF)].
Heat which is added to a vapor after the change of state occurs is called?
Adding heat to a vapor after the change of state from liquid to vapor has occurred is called super-heating. For example, adding heat to steam at 100 C and 101.325 kPa is called super-heating.
How much heat is released when 75 g of steam at 100 C is cooled to ice at -15?
To determine the heat released, you need to calculate the heat lost during the cooling process. First, calculate the heat lost when steam at 100°C condenses to water at 100°C. Use the formula Q = m * c * ∆T, where m is the mass, c is the specific heat capacity, and ∆T is the temperature change. Then, calculate the heat lost when water at 0°C freezes to ice at -15°C using the same formula. Finally, add the two calculated values to find the total heat released.

What super refractory?
Super Refractory is a refractory material which retains its shape and chemical identity in extreme heat, so super refractories are used in Industries for heat resistance.
What instrument can be used to calculate specific heat capacity?
A calorimeter is commonly used to calculate specific heat capacity. This device measures the heat transfer in a system when a material undergoes a temperature change, allowing for the determination of specific heat capacity.
How many Super Bowl games did the Miami Heat win?
The Miami Heat play in the NBA so they do not play for the Super Bowl. The Miami Dolphins have won two Super Bowls and the Miami Heat have won one NBA championship.
What do you need to know to calculate the heat needed to melt a block of ice at its melting point?
To calculate the heat needed to melt a block of ice at its melting point, you need to know the mass of the ice block, the specific heat capacity of ice, and the heat of fusion of ice (or latent heat of fusion). The formula to calculate this heat is Q = m * ΔHf, where Q is the heat energy, m is the mass, and ΔHf is the heat of fusion.
How can we calculate the heat flow into the gas?
To calculate the heat flow into a gas, you can use the formula Q mcT, where Q is the heat flow, m is the mass of the gas, c is the specific heat capacity of the gas, and T is the change in temperature.

How do you calculate the heat of combustion for a given substance?
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.
