If its in Celsius then another 13 degrees are needed because water boils at 100 degrees Celsius

O.385x1x2=0.77 Answer: 0.77
Specific heat capacity tells you how much stuff energy can store. specific heat capacity is the amount of energy needed to raise the temperature of 1kg of a substance by 1 degrees celsius. water has a specific heat capacity of 4200 J/kg degrees celsius.
To find the energy needed to raise the temperature of a substance, we can use the equation Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. For copper, the specific heat capacity is approximately 0.386 J/g°C. Converting the mass from grams to kilograms (50 g = 0.05 kg), we can plug in the values to calculate the energy: Q = (0.05 kg) * (0.386 J/g°C) * (30°C) = 0.579 J Therefore, you would need approximately 0.579 joules of energy to raise the temperature of 50 grams of copper by 30 degrees Celsius.

You need to know the mass of this coin.Heat (in calories) = 5 x 0,092 x mass (in g)
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
