Heat energy and transfer: Specific heat capacity. | hvac

Specific heat capacity. The specific heat capacity of a substance is the quantity of heat energy required to raise the temperature of 1 kg of the substance by 1°C.The symbol used for specific heat capacity is c and the units are J/(kg °C) or J/(kg K). (Note that these units may also be written as J kg–1 °C–1 or J kg–1 K–1).. Some typical values of specific heat capacity for the

How to Calculate Heat Absorption | Sciencing

This is a quantity given the symbol c and measured in joules / kg degree Celsius. In short, the heat capacity tells you how much heat energy (in joules) is needed to raise the temperature of 1 kg of a material by 1 degree C. The specific heat capacity of water is 4,181 J / kg degree C, and the specific heat capacity of lead is 128 J/ kg degree C.

what is the density of water?

What Is the Density of Water?

The density of pure water actually is somewhat less than 1 g/cm 3.A standard table lists the values for the density of liquid water. Note that water can be supercooled and remain a liquid well below its normal freezing point. The maximum density of water occurs around 4 degrees Celsius.

Calculate the heat required to raise the - Socratic

To calculate the energy required to raise the temperature of any given substance, here's what you require: The mass of the material, #m# The temperature change that occurs, #DeltaT# The specific heat capacity of the material, #c# (which you can look up). This is the amount of heat required to raise 1 gram of that substance by 1°C.
