Calculate the specific heat capacity of a piece of ice if 1.30 kg of the wood absorbs 6.75×104 joules of heat, and its temperature changes from 32 ºC to 57 ºC.

Explanation:

-Specific heat capacity is given by the formula:

Where:

is the heat gained or loosed by the substance

is the mass of the substance

is the specific heat of the substance

is the change in temperature

#We make c the subject of the formula and substitute to solve for it:

Hence, the specific heat capacity of the ice is

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
