If a is a number between 3 and 4, what is the possible values for 12a?

Some of the possible values of 12a are 37.2, 37.32, 38.4, 38.76, 39.6 and so on

Solution:

Given that "a" is a number between 3 and 4

We have to find the possible values for 12a

Between 3 and 4 , there are many numbers

It can also be a decimal number

3.1, 3.11, 3.2, 3.23, 3.3, 3.4, 3.5, ............. , 3.6, 3.7 and so on

We can some of the above numbers

And so on

Thus some of the possible values of 12a are 37.2, 37.32, 38.4, 38.76, 39.6 and so on

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.
