Answer to Question #152145 in Chemistry for ray

Question

the temperature of 17g of water can be raised by 2.0c with __ or ___ of thermal energy

Answer 1

q = m x c x ΔT

c_(water) = 4.18 J/g/K

q = 17 x 4.18 x 2 = 142.12 J = 0.142 kJ

the temperature of 17g of water can be raised by 2.0c with 142.12 or 0.142 kJ of thermal energy
