# What state changes do atoms undergo to decrease in value?

## During which changes of state do atoms decrease?

Atoms lose heat during evaporation, but gain energy when they boil. A. A. You just studied 10 terms!

## What happens if atoms lose energy during a change of state the atoms are pushed?

Answer to: What happens when atoms lose energy in a state change? Repulsive forces push the atoms apart and make them less organized. Attractive forces pull the atoms together and make them less organized.

During which changes of state do atoms overcome the attractive forces between them quizlet?

Sublimation is when atoms within a solid gain enough energy to make a gas, without having to pass through the liquid state. The atoms can move quickly enough to overcome the attraction forces between them, thanks to low air pressure and large amounts (often in the form heat) of energy.

### How does temperature affect the change of state?

When thermal energy is added, a substance’s temperature rises, which can cause it to change from liquid to liquid (melting), gas to gas (vaporization), and gas to solid (sublimation). It can vaporize if the pressure drops. Some types of rock can melt when their pressure decreases.

### How does temperature affect the movement of water?

Temperature causes water molecules in the gas to move faster because each molecule has more energy when it heats up (according Kinetic molecular theory). Even at room temperature, some water molecules can fly into the gas. This is why there’s always water in the atmosphere.

What is relation between temperature and pressure?

The pressure of a certain amount of gas is proportional to its volume. The temperature of a system increases, so does the pressure. Gay-Lussac’s law explains the relationship between temperature and pressure of a gas.

## What happens when body temperature decreases?

When your body temperature drops, the nervous system, heart and other organs stop functioning normally. Hypothermia, if left untreated can cause complete collapse of your heart and respiratory system. This could eventually lead to death. Hypothermia can be caused by cold weather exposure or immersion in cold waters.

## What kills you in hypothermia?

Anything below 70 degrees is considered profound hypothermia, and could be fatal. Hypothermia can lead to impaired heart function, shock, liver failure, kidney disease, and eventually death.

At what temperature can hypothermia set in?

Hypothermia is a condition that occurs when you are exposed cold air, wind, rain, or water. Your body temperature can drop to a low level at temperatures of 50degF (10degC) or higher in wet and windy weather, or if you are in 60degF (16degC) to 70degF (21degC) water.
