Water has a specific heat of 4.184 J/g deg while glass (Pyrex) has a specific heat of 0.780 J/g deg. If 10.0 J of heat is added to 1.00 g of each of these, which will experience the larger increase of temperature?

Definition:Specific heat is the amount ofheatenergyrequired to raise thetemperatureof a body per unit ofmass.

InSIunits, specific heat (symbol: c) is the amount of heat injoulesrequired to raise 1gramof a substance 1Kelvin.

Also Known As:specific heat capacity, mass specific heat


q = mcΔT where q = heat energy m = mass c = specific heat ΔT = change in temperature

here the amount of heat added,mass of the substance is constant therefore larger increase in temperature is for the substance having low specific heat as it is inversly proportional.
thus pyrex will experience larges incrase in temperature
