Formula for finding specific heat capacity
WebJan 17, 2024 · To find the number of moles, divide the quantity of the sample by its molar mass. Now that you have found n, substitute the value of heat capacity (C) and the number of moles (n) in the formula and calculate molar heat capacity. Another method for determining molar heat capacity is multiplying the specific heat (c) of the sample by its … WebDec 9, 2024 · The specific heat capacity of water is 4184 J/(kg · K). It means that we need to supply 4184 joules of heat to increase the temperature of 1 kg of water by 1 Kelvin. We can calculate the heat …
Formula for finding specific heat capacity
Did you know?
WebThe specific heat capacity of a substance is the amount of heat required to raise one gram of the substance by one degree Celsius. Water, for example, has a specific heat capacity of 4.18. This means to heat one gram of water by one degree Celsius, it would require 4.18 joules of energy. WebThe heat capacity of 1 gram of a substance is called its specific heat capacity (or specific heat), while the heat capacity of 1 mole of a substance is called its molar heat capacity. The amount of heat gained or lost by a sample (q) can be calculated using the equation …
