What is the value for specific heat of water 4?

Specific Heat of Water For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C.

How do you find the specific heat capacity of water?

Calculate specific heat as c = Q / (mΔT) . In our 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.

How do you calculate the specific heat of water?

The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT.

What is the value for specific heat of water answer?

The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation.

How do you find heat capacity from specific heat capacity?

The units of specific heat capacity are J/(kg °C) or equivalently J/(kg K). The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT.

Why is specific heat of water so high?

Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid.

What is Q specific heat?

The quantitative relationship between heat transfer and temperature change contains all three factors: Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.

What is the specific heat of water in J kg?

The specific heat of water is 4182 J/kg°C, which is a high specific heat capacity and is sometimes taken as 4,200 J/kg °C.

What does it mean that the specific heat of water is 4200?

Originally Answered: What does it mean that the specific heat of water is 4200 j per kg degree celcius? Specific heat is a value that expresses the proportion between heat, mass, and temperature slide for a certain substance. In your example of water, this proportion is worth 4,200.

How do you calculate specific heat capacity of water?

Calculate specific heat as c = Q / (mΔT). In our 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. If you have problems with the units, feel free to use our temperature conversion or weight conversion calculators.

How many joules does it take to heat water by 1 degree?

If you have 1 kg of water and you want to heat it up by one degree C, then you have to add 4200 joules of heat. If you have 2 kg, then you have to add 8400 joules. That’s the per kilogram part. For each kilogram, you have to add 4200 J. It takes 4200 J per kg to heat up water by 1°C. Or 4200 J/kg for every degree C. Let’s go back to 1 kg.
