Calculate the energy needed to increase the temperature by 30 °C for 0.4 kg of gold.The specific heat capacity of gold is 130 J/kg°C.You must include units in your answer.

1,300 J of energy is transferred to the thermal store of a block of gold of mass 0.2 kg.  This causes its temperature to rise from 100 to 150 °C.  Use this information to calculate the specific heat capacity of gold.5.2 J/kg °C65 J/kg °C43.3 J/kg °C130 J/kg °C

How many calories are required to raise the temperature of a 150. g sample of gold from 25 °C to 175 °C? The specific heat of gold is 0.0308 cal/g °C.

The heat of fusion for gold at 1,063 °C is 66.6 kJ/kg and the specific heat of gold is 0.128 kJ/kg °C. What is the energy needed to melt 100 grams of gold starting at 0 °C

Assume it takes 108 joules of energy to raise the temperature of a bar of gold from 25.0°C to 29.7°C. Given that the specific heat capacity of gold is 0.128 J/g °C, what is the mass (in grams) of the bar of gold?   5.6 x 10-3 g  65 g   129 g   1.8 x 102 g  none of the above
