Divide this answer by 1,055, the number of joules in a Btu: 5,211 ÷ 1,055 = 4.94, or approximately 5. The substance needs 5 Btus for you to heat it to 31 degrees.
159984 Joules c. 331056 Joules d. 246840 Joules Find the amount of heat energy required to vaporize 37.5 g of liquid water at 100 degree C? Given: The molar heat of vaporization for water is 40.6 kJ/mol. Calculate the amount of heat required to change 50.0 g ice...
measured in units of heat per unit mass. Specific heat capacity units are usually joules per gram-kelvin, or J/g⋅K, even though the kilogram (kg) is the SI unit of mass. One reason specific heat is useful is that if you have a known mass of a uniform substance and know its heat...
Calculate the amount of heat in Joules needed to transfer 1.0 L of water in a 2.0 kg steel container from −35∘C to boiling water Sensible and Latent Heat:Whenever a specific liquid (water) gets a particular amount of heat, t...
The specific heat capacity (c) of a substance is the amount of energy needed to change the temperature of 1 kg of the substance by 1 unit of temperature. Different substances have different specific heat capacities, for example, water has a specific heat capacity of 4,181 joules/kg degrees...
joules / kg degree Celsius. In short, the heat capacity tells you how much heat energy (in joules) is needed to raise the temperature of 1 kg of a material by 1 degree C. The specific heat capacity of water is 4,181 J / kg degree C, and the specific heat capacity of lead is ...
In summary, to calculate the specific heat capacity of nickel, we first need to calculate the heat energy for water at 13.5 degrees C using the formula Q=mcT. Then, we can use the specific heat capacity of water at that temperature, which is 4.1813 JK^-1g^-1. Assuming that the nickel...
Calculate the quantity of heat that is absorbed/released when 5.00 g of steam condenses to liquid water at 100 ^oC. Calculate the energy (heat) required to transform 18.02 grams of ice at 253 K into steam at 393 K. Calculate joules release when 175 g of steam condenses at ...
Multiply this product by the substance's specific heat capacity. With this example, which uses water, whose specific heat capacity equals 4.186 joules per gram: 4,200 x 4.186 = 17,581.2, or approximately 17,500 joules. This is the amount of energy that is transfered during the heating proc...
