An online specific heat calculator helps to find the specific heat, heat energy, mass of substance, initial temperature, and final temperature of any substance. When it comes to analyze specific heat of water or any other substance, it tells us the specific heat formula along with whole solution for a respective substance.

You give a try to this specific heat capacity calculator to determine the heat capacity of a heated or a cooled sample.

Well, read the given context to understand how to calculate specific heat capacity (step-by-step) and by using q=mc∆t equation calculator. But, let’s begin with some basics!

What is Specific Heat?

It is the amount of heat that is required to change the temperature of a mass unit of any substanceonly by one degree. To find specific heat capacity we can say that it is a measure of the total energy that is needed to heat up 1 kilogram of any material to 1°Celcius or 1Kelvin. These phenomena should take place within a temperature range, where the substance doesn’t change its state e.g. in case of water it shouldn’t get boiled.

For convenience, use this free, but best ohms law calculator to work out for Voltage (V), Resistance (R). Current (I), and Power (P).

Specific Heat Formula:

Heat capacity formula is:

$$ C = \frac {Q}{m\times\Delta T} $$

Whereas:

  • \(C\) is representing the specific heat capacity
  • \(Q\) is representing the induced thermal energy
  • \(m\) is representing the mass
  • \(\Delta T\) is the temperature difference
  • \(J\) is Joule
  • \(°C\) is degrees centigrade or Celsius
  • \(K\) is kelvin

Example:

If you have a \(15 g\) piece of any metal that absorbs \(134 J\) of heat while increasing from \(24.0°C\) to \(62.7°C\). How will you calculate its specific heat?

  • Given heat \(q = 134 J\)
  • Given mass \(m = 15.0 g\)
  • Change in temperature: \(\Delta T = 62.7 – 24.0 = 38.7\)

To find specific heat put the values in above specific heat equation: \(\frac {q}{m \times \Delta T} = \frac {134}{15 \times 38.7} = 0.231\). However, a specific heat calculator can assist you in finding the values without any hustle of manual calculations.

However, density is crucial to identify the purity of substances, so give a try to an online density calculator to find the relationship between the density, mass & weight of the object.

Specific Heat Capacity Unit:

Definition of Specific heat capacity revealed that it is the amount of heat required to increase the temperature of 1 kilogram of any substance by 1 kelvin. Hence, its derived \(SI \)unit is \(J kg−1 K−1\). A specific heat capacity calculator is functioned to deliver the outcomes along with standardized units.

Specific Heat of Water?

specific heat of water has one of the maximum specific heat values among common substances. It is about \(4182 J/ (K kg) at 20 °C\). In case of ice it is only \(2093 J/ (K kg)\).

How to calculate specific heat (step-by-step)?

With the support of specific heat formula calculation of specific heat is and easy process. Have a look down below and follow some simple steps:

Step 1:

First of all, you have to Determine whether you want to warm up the substance or cool it down. Now give the amount of energy supplied as a positive value. While cooling down the sample, you have to give the subtracted energy as a negative value. For instance, say that we want to decrease the taster’s thermal energy by \(63,000 J\). Then \(Q\) will be \(-63,000 J\).

Step 2:

Now decide the difference of between the initial and final state of the sample. Let’s suppose the difference is \(ΔT = -3 K\) and m is 5 kg.

Step 3:

Just put the values in specific heat equationas\( c = Q / (m x ΔT)\). In this example, it will be equal to c = \(-63,000 J / (5 kg * -3 K) = 4,200 J/(kg•K)\).

This is the typical heat capacity of water and it can be calculated by specific heat calculator as well in one go.

How much energy is required to raise the temperature of one gram of water 1 c?

The calories are defined as the amount of heat that is required at a pressure of 1 to increase the temperature of 1 gram of water at \(1°\) Celsius. Also, the calories have been defined in terms of the joule, and one calorie is equal to approximately \(4.2 joules\). Therefore, we can say that \(4.2 joules\) of energy are required to raise the temperature of 1-gram water. However, a heat capacity calculator is the finest way to have an error-free answer.

FAQ’s:

Why is water’s heat capacity so high?

High heat capacity of water is because of hydrogen bonding among its molecules. When heat is absorbed in water, bonds of hydrogen brakes and water molecules start moving freely. With the decrease in water temperature, the hydrogen bonds release a significant amount of energy.

How much heat is required to melt 200g ice?

Typically, \(250×332 joules\) of energy required to melt the \(200ng\) of ice.

How much energy does it take to melt ice?

If you want to melt, 1 g of ice at \(0°C\) total \(334 Joules\) of energy are required. It is also called the latent heat of melting. Specific heat calculator can calculate the joules of energy for multiple grams of any substance within few seconds.

Takeaway:

We all have some awareness of what specific heat is, as we have done Physics in our academics. It is the quantity of heat that is compulsory to elevate the temperature of a certain material by a definite amount and that the amount of heat will vary for dissimilar substances. The specific calculator is the best way to find the amount of heat required to raise the temperature of \(1 (g)\) of a substance \(1 (°C)\).
