Nolan spent $320. He spent around 40% of his money.
800-480=320.
320/800=0.4
0.4 x 100= 40%
hope this helps!
Convection is a process which transfers the heat between the temperatures when fluid (i.e. liquid or gas) is in motion. Due to the presence of heat source, water temperature increases and also it will become less dense and rise. Hot air is less dense than cold. When air rises higher in the atmosphere its pressure gets down and it becomes colder.
I’m going to guess urbanization but i could be wrong!
The density of an object or quantity of matter is its mass divided by its volume. ... Non-standard conditions can result in a change of volume, affecting the density of the materials. Also, certain temperatures and pressures can result in a change the state of the matter, which also affects the density.
