What do you mean by specific heat capacity of water is 4200?
4,200 Joules per kilogram per degree Celsius
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
What is meant by specific heat and What is unusual about the specific heat of water?
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.
What is the specific heat capacity of water?
Heat Capacities for Some Select Substances
| Substance | specific heat capacity Cp,s (J/g °C) | molar heat capacity Cp,m (J/mol °C) |
|---|---|---|
| titanium | 0.523 | 26.06 |
| water (ice, O°C) | 2.09 | 37.66 |
| water | 4.184 | 75.38 |
| water (steam, 100°C) | 2.03 | 36.57 |
What is the specific heat of water in kJ kg K?
4.187 kJ/kgK
Specific heat (Cp) water (at 15°C/60°F): 4.187 kJ/kgK = 1.001 Btu(IT)/(lbm °F) or kcal/(kg K)
What is specific heat capacity in chemistry?
The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
What is specific heat capacity in physics?
In thermodynamics, the specific heat capacity (symbol cp) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature.

What do you mean by specific heat capacity?
What is the specific capacity of iron?
about 449 J⋅kg
The specific heat capacities of iron, granite, and hydrogen gas are about 449 J⋅kg−1⋅K−1, 790 J⋅kg−1⋅K−1, and 14300 J⋅kg−1⋅K−1, respectively.
Water has a specific heat capacity of 4182 J/kg°C. Because water is such an important and common substance, we even have a special way to identify the amount of energy it takes to raise one gram of water by one degree Celsius—a Calorie.
What does a high heat capacity mean in chemistry?
A high heat capacity means that a substance can absorb a lot of heat before registering a change in temperature—think about how long it takes for a pot to get warm to the touch on the stove versus how long it takes the water inside to get warm. That means that water has a higher heat capacity—it can store more heat before changing in temperature.
What is the specific heat capacity of copper in K?
What is the specific heat capacity value of copper? The specific heat of copper is 385 J/kg K. You can use this value to estimate the energy required to heat a 100 g of copper by 5 °C, i.e., Q = m x Cp x ΔT = 0.1 * 385 * 5 = 192.5 J.
What is the meaning of J/kg-C?
Honestly, the 1’s in the units are redundant, the more common notation is J/kg-C. What that means is that, if you multiply the mass of water in kilograms by the temperature change in degrees centigrade, by 4200, you get the amount of heat that needs to be added or removed for that temperature change. Joules is a measure of energy.
