Specific heat

The specific heat of a substance is the amount of energy required to increase the tempeture of 1 gram of any substance by 1 degree.

From water it is: 

The character is c (small letter)

This is a substance property.

4,2Jg⋅​0​​C

/

c = Specific heat

Calculations with specific heat

Formula :   Q = c x m x ΔT

Q = heat in joules (J)

c = specific heat in joules per gram per degree Celsius (J/g.^oC)

m = quantity of a substance in grams (g)

ΔT= temperature increas: = T_end - T_start (^oC)
