What formula best defines specific heat?
What formula best defines specific heat?
Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
Which of the following defines specific heat?
Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.
What is specific heat in chemistry?
The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1°C.
Why a gas has two specific heat capacity?
A solid or a liquid when heated does not undergo any change in the volume or pressure. But in case of a gas, both the pressure and volume change on heating. Therefore, specific heat of a gas is defined either at constant volume or at constant pressure and hence a gas has two specific heats
What is CP Gas?
cp = cv + R The specific heat constants for constant pressure and constant volume processes are related to the gas constant for a given gas. This rather remarkable result has been derived from thermodynamic relations, which are based on observations of physical systems and processes.
What is the lowest specific heat?
Steam has a low specific heat capacity (0.47 calorie per gram per °C) than water(1 cal per gram per °C) and heats much more than water for the same time of heating.
Does wood have a high specific heat?
A: Wood has a higher specific heat than metal, so it takes more energy to heat a wooden handle than a metal handle. As a result, a wooden handle would heat up more slowly and be less likely to burn your hand when you touch it
Does water have a high specific heat?
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we’ll refer to as simply “heat capacity”, meaning it takes more energy to increase the temperature of water compared to other substances.
