## What is the formula for specific latent heat?

The specific latent heat (L) of a material… is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change.

is defined through the formula Q = mL.

is often just called the “latent heat” of the material..

## How does temperature affect specific heat capacity?

1 Answer. The heat capacity is the slope of the plot of internal energy U with temperature T. … Then as temperature increases more of the energy levels become excited & the internal energy rises rapidly and so does the slope of U vs T and so heat capacity increases.

## Why is CP is greater than CV?

The heat capacity at constant pressure CP is greater than the heat capacity at constant volume CV , because when heat is added at constant pressure, the substance expands and work.

## How do you find specific heat from different temperatures?

Q = m*s*dT, where Q = heat, m = mass, s = specific heat, and dT is the change in temperature (T2 – T1). You can use this formula to calculate the specific heat.

## How do I calculate specific heat?

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. Values of specific heat are dependent on the properties and phase of a given substance.

## What does ΔT mean?

Universal TimeΔT (timekeeping) the difference between two time scales, Universal Time and Terrestrial Time, which results from a drift in the length of a day. The interval of time used in determining velocity.

## What are the 4 types of heat transfer?

Various heat transfer mechanisms exist, including convection, conduction, thermal radiation, and evaporative cooling.

## What is the formula for temperature change?

The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, 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.
