What forms when a main sequence cools and expands?
It grows to such an extended size that it exceeds the standard dimensions of the page, and a fold-out is required.
Why when altitude increasestemperature decreases in the troposphere?
With altitude, gravitational pull on the air decreases, which means the air expands and air pressure drops. When any gas expands, it cools off.
When a contracting hot ball of gas spins into a disk shape it cools faster due to?
increased surface area
Does water continue to expand as it cools after forming ice?
Water expands when it first freezes, but after that ice will contract as it continues to cool.
When warmer air rises above the frontal surface expands and cools as it ascends does it relative humidity increase or decrease?
Increase

When a parcel of air moves upward it expands and cools?
When a parcel of air moves upward, it expands and cools due to the altitude.
What happens when air rises?
It expands and cools
What are examples of thermal expansion and contraction?
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
What does air do as it rises?
rising air expands then cools and condenses
Objects that form as warm air rises expands and then cools?
clouds
Objects that form as warm air rises expands then cools?
CLOUDS
What are the disadvantages of rubber tires?
When rubber is heated it expands and when it cools it contracts.
Why air expands as it cools?
Air doesn't expand when it cools it contracts. any easy way to prove this point is to blow up a balloon put it in the fridge and leave it there for a while it will become smaller take it out of the fridge and it will get bigger again. Air expands as it heats and contracts as it cools.
Matter expands when it gets hotter and contracts when it cools?
The explanation of Thermal Expansion.
Why a gas cools when it expands at high pressure?
as preasure increase tempreture decrease
