# What is the unit of water equivalent of a body?

## What is the unit of water equivalent of a body?

The water equivalent of a body is indeed equivalent to the product of its mass and its specific heat. It is also possible to describe the water equivalent of a given body as the mass of water whose heat capacity equals the heat capacity of a given body.

## What equivalent of a body is measured in?

Solution. Since water equivalent of a body is the mass of the water having the same heat capacity as the given body, the water equivalent is measured in kilogram.

**Is water equivalent same as thermal capacity?**

The numerical value of the thermal capacity and the water equivalent of the substance are the same.

**What is water equivalent Class 11?**

Water equivalent is defined as the amount of water that can replaces any substance gaining the same variation in temperature, when provided with the same amount of energy as that of substance.

### What is the value of water equivalent?

In general water equivalence value should be in the range 10-14 g taking 25 mL of cold water and 25 mL of hot water, in the given apparatus (thermos flask or calorimeter).

### What is water equivalent formula?

From equations (i) and (ii): ΔQ = mcΔθ = W x 1 x Δθ. The product of the mass of a substance by its specific heat equal numerically to the mass of water that is equivalent in thermal capacity to the substance is known as water equivalent of that substance.

**What is meant by the water equivalent of a calorimeter water equivalent of a body is 10kg What does it mean?**

Water equivalent of a given body is the amount of water whose temperature could be raised through 1K ( or 1oC) by the heat required to raise the temperature of the body through 1K ( or 1oC).

**What is meant by water equivalent of calorimeter?**

Hint: Water equivalent is nothing but the amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase. A calorimeter is used to measure the heat flow.

#### What is the SI unit of thermal capacity and water equivalent?

SI unit of water equivalent is joule per Kelvin (J/K). The amount of heat required to raise the temperature of a body of a given mass by 1 degree is known as thermal capacity. SI unit of thermal capacity is joule per Kelvin (J/K).

#### Why the unit of water equivalent is Kg?

The thermal capacity of the body and its water equivalent are numerically equal. If the thermal capacity of the body is expressed in terms of the mass of water then it is called Water equivalence of the body. $\therefore$ The SI unit of water equivalent of the calorimeter is $Kg$. Hence the option (A) is correct.

**What is water equivalent of a substance?**

Answer: A substance’s water equivalent is equivalent to the amount of water that is required to consume the same quantity of heat as that substance does for a temperature rise of one degree. The water equivalent of a body is indeed equivalent to the product of its mass and its specific heat.

**What is the SI unit of water equivalent to Kg?**

It is denoted by W. W = ms = heat capacity of the body. Its expressed in the unit gram….Thermometry and Calorimetry:

Heat Energy | Temperature and its Measurement |
---|---|

Thermometric Property | Thermometers |

Thermal Expansion | Thermal Equilibrium |

Triple Point of Water | Specific Heat Capacity |

Thermal Capacity | Water Equivalent |

## What is water equivalent of a given body?

Water equivalent of a given body is the amount of water whose temperature could be raised through 1K ( or 1 oC) by the heat required to raise the temperature of the body through 1K ( or 1 oC ). Water equivalent of a given body is that mass of water whose heat capacity is equal to the heat capacity of the given body.

## What is the equivalent unit of water in grams?

Water Equivalent Unit: SI unit for water is kg Its expressed in the unit gram. Water Equivalent Dimensional Formula:

**What is meant by the term’water equivalent’?**

Water equivalent- is the amount of water which will absorb the same amount of heat as that of the body (we are talking of) per 1 unit of temperature rise. Hey there Raghav.

**What is the water equivalent of a calorimeter?**

If the same X heat is given to Z kg water, such that the temperature rise of the water is exactly Y°, then Z is the water equivalent of the calorimeter. Water equivalent is generally used in comparison of a water quantity.
