Question

____________ heat is the amount of heat required to change the temperature of 1 gram of a substance by 1°C, and it is related to the chemical composition of the substance.

Answer 1

Step-by-step explanation:

The amount of heat necessary to raise the temperature of 1 gram of a substance by
`1^(o)C` is known as specific heat of a substance.

Mathematically, q =
`mC \Delta T`

where, q = Heat energy

C = specific heat

`\Delta T` = change in temperature

And, more is the mass of a substance high amount of heat is required by it.

Thus, we can conclude that specific heat is the amount of heat required to change the temperature of 1 gram of a substance by 1°C, and it is related to the chemical composition of the substance.

Answer 2

specific heat.

Step-by-step explanation:

Definition:

The amount of heat required to raise the temperature of one gram of substance by one degree is called specific heat.

Formula:

Q = m. c. ΔT

Q = amount of heat required

m = mass of substance

c = specific heat of substance

ΔT = change in temperature

The substance with greater value of specific heat require more heat to raise the temperature while the substance with lower value will raise its temperature very quickly by absorbing smaller heat.

For example the beach sand gets hot very quickly because of lower specific heat of sand while water is colder than sand because of higher specific heat capacity.
