One gram of Material A is heated until the temperature rises by 15 kelvins. If the same amount of heat is applied to one gram of Material B, what is the temperature rise of Material B in units of kelvins?

The specific heat ( Cp ) of Material A = 6 joules per gram kelvin [J/(g K)]

The specific heat ( Cp ) of Material B = 2 joules per gram kelvin [J/(g K)]
