The higher the substance's specific heat capacity, the more heat energy is needed to raise it's temperature.
You need to know its specific heat.
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.

1 calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water by 1C, so... It takes 8.1 calories to raise your 8.1 grams by 1C, but you need to raise it 20C. 8.1*20=162. 162 calories is the answer you are looking for.
A heater can raise the temperature of a fish tank if needed
It is dH = m C dT dH = 225 ( 0.21cal/gram-C) (80 C) 3780 calories your answer: 3.8kcal
The formula is: 0,108 x 3000 x (T1 -T2), in kilocalories.
Mass, heat capacity, the desired raise in temperature.
1 calorie is needed to raise 1 g of water 1 °C. 350 * 22 = 7700 calories ■

100 calories. 1 calorie is defined as the amount of energy required to raise the temperature of 1 gram of 1 by 1 degree Celsius. So, if you need to raise 10 grams of water 1 degree, you would need 10 calories of energy. If you needed to raise those same 10 gram by 10 degrees, you'll need 10 * 10, or 100 calories.
