Measuring the Specific Heat of Sand. Given that the specific heat of water is 1 calorie/gm/°C (which we will take to be representative of sea water and hence "ocean"), we can measure the specific heat of sand (which we will take as representative of "land") using the experimental procedure described below.

Specific Heat Capacity Equation -- EndMemo Calculator

Specific Heat Capacity Calculator. Specific heat refers to the amount of heat required to raise unit mass of a substance's temperature by 1 degree.

Specific Heat Capacity - an overview | ScienceDirect Topics

Specific heat capacity is the amount of heat to be supplied to (or taken out of) the unit mass of a system in order to increase (or decrease) its temperature by one degree in a thermodynamic process in which quantity X is imposed, according to:

Specific heat - Simple English Wikipedia, the free ...

Specific heat (s) is a particular type of heat capacity.Specific heat is the thermodynamic property, which states the amount of heat required for a single unit of mass of a substance to be raised by one degree of temperature. Varying ranges of specific heat values are seen for substances depending on the extent to which they absorb heat.

2.4 Specific Heats

The specific heat ratio, (or ), is a function of only and is greater than unity. An ideal gas with specific heats independent of temperature, and, is referred to as a perfect gas . For example, monatomic gases and diatomic gases at ordinary temperatures are considered perfect gases.

Specific Heat Worked Example Problem

There are published tables of molar specific heats of many materials. Note that the specific heat equation does not apply for phase changes. This is because the temperature does not change. When working a problem, you'll either be given the specific heat values and asked to find one of the other values, or else asked to find specific heat.
