Question

What amount of heat is required to increase the temperature of 75.0 grams of gold from 150°C to 250°C? The specific heat of gold is 0.13 J/g°C. A. 750 joules B. 980 joules C. 1300 joules D. 1500 joules E. 2500 joules

Answer 1

Answer:

B. 980

Explanation: heat required= mass×  specific heat  ×change in temprature

                                             = m s ΔT

                                            = 75× 0.13 ×[250-150]

                                                 = 975 joule
