Specific heat capacity is basically a measure of how hard it is Heating various materials. to calculate Specific heat capacity (C) For any substance, you will need a specific heat capacity formula (equation, if you wish).
Next you will also get specific heat capacity calculator: You just plug in Q (heating energy), m (mass), And T (temperature difference), and the calculator will dynamically calculate the specific heat capacity for you. Here’s what the specific heat calculator looks like (screenshot):
First, we’ll look at the specific heat capacity formula. This is a fairly simple formula that can be used by everyone. Finally, we also list the specific heat capacities of air, water, and some other substances. We will also solve some simple examples of calculating specific heat capacity. Let’s look at an example to illustrate what specific heat capacity actually tells us:
Example: The specific heat capacity of air at room temperature is 1012 J/kg×K. The specific heat capacity of water at room temperature is 4181 J/kg×K. This means that to heat one kilogram of water, we need about 4 times more heat than one kilogram of air.
Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kg of a substance by 1K. Often we use SI units for this (J = Joule, Kilogram = Kilogram, K = Degree of Kelvin).
We can put all these numbers neatly in a formula like this:
specific heat capacity formula
Specific heat capacity is denoted by C (C for potential). Here is the equation for calculating the specific heat capacity C:
c = q (m × t)
Very easy, isn’t it?
- Q is the amount of heat that we give to a substance. Could be 1 J, 40 J, or even 50,000 J, any amount of joules could go.
- m is the mass of the substance we are heating. You can heat 1 kg of substance, 20 kg, or even 10 g of substance, no matter what the weight.
- T is the temperature difference between the initial temperature and the final temperature, and is always measured not in degrees Fahrenheit (°F), not in degrees Celsius (°C), but in Kelvin (K). Example: If we heat water from 68°F or 20°C (ie 293K) to 158°F or 70°C (ie 343K), the temperature difference is 343K – 293K = 50K.
Here’s a quick example: Let’s say we need 6000 J of heat to heat 3 kg of matter to 10K. Here’s how we calculate the specific heat capacity using the equation above;
C = 6000J (3kg × 10K) = 200 J/kg×K
The specific heat capacity formula tells us that the specific heat capacity (C) of this substance is 200 J/kg×K.
To make things even simpler, you can use this calculator
Specific Heat Calculator
Basically, you just enter Q, M, and T, and the calculator will dynamically calculate the specific heat capacity for you. You can of course play with the numbers a bit too.
With this calculator, you can easily determine what the specific heat capacity of a substance is, so you don’t need to calculate everything yourself.
Let’s take a look at the specific heat capacities of some common gases, liquids and solids:
