What else can I help you with?
Why when you open a door on a cold day does the cold air come in at the bottom?
this is because cold air is denser (when things lose energy or heat, they shrink), and heavier than the air in your house. when you oppen the door, the ouside air will rush in under the hot air in your house and the hot air will try to rise up and ouside.
Why does your door shut easier in the winter than in the summer?
in the summer, there is more humidity and it causes the wood to swell. When it is cold outside, the swelling goes down and it is easier to close the door without it rubbing against the frame. Heat expands everything, the doors and house included. When they expand the door will rub against the frame. When it's cold things will contract or constrict and therefore the door and house will shrink and be easier to open. ( The house will shrink but since there is a space where the door is the house won't shrink inwards at the door frame but when it expands it will close the gap of the door frame).
What is the density of cold air?
1500 G/Ml I don't know the density of hot though. I know this cause i am on my science project
Which one of the following situations would cause air pressure to rise an increase in temperature cold air entering the region moisture entering the air?
An increase in temperature would cause air pressure to rise. As air warms, its molecules gain more kinetic energy and spread further apart, leading to an increase in pressure. Cold air entering a region or moisture entering the air would not directly cause air pressure to rise.
What is produced when a cold air mass moves into an area where a warm air mass is located?
When a cold air mass moves into an area where a warm air mass is located, it can lead to the formation of a cold front. This boundary can cause the warm air to be lifted rapidly, leading to stormy weather with possible thunderstorms. The interaction between the two air masses can result in abrupt changes in weather conditions.
Does cold air shrink or stay the same?
Cold air contracts and becomes denser, so it tends to shrink in volume. This is why inflated objects like balloons or tires appear to deflate in cold weather.
Why does cold air shrink balls?
to Obtain Heat
Does linen shrink?
Yes it can shrink. You should hand wash or use gentle cycle with cold water and air dry.
Why would a basketball shrink half its size in cold weather while in a trunk?
Cold air is dense.
Why do balloons get small by cold air?
Balloons shrink in cold air because the air molecules inside the balloon lose energy and move closer together, resulting in a decrease in volume. This reduces the pressure inside the balloon, causing it to deflate or shrink.
Will balloons pop if their to cold?
Yes, extreme cold temperatures can cause balloons to become more brittle and less elastic, making them more susceptible to popping. Additionally, cold air can cause the molecules inside the balloon to shrink, putting extra stress on the material and increasing the likelihood of bursting.
What occurs to the volume of an inflated balloon when exposed to cold air?
It decreases. The colder air contracts, making the balloon shrink.
Does cold air cause moisture in the air?
no
When an inflated balloon is exposed to cold air the volume of the balloon?
decreases. This is because the cold air causes the air molecules inside the balloon to move slower, reducing their kinetic energy and causing the balloon to shrink.
What causes a cars heater to blow cold air?
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
What happens if you put a inflated balloon in the freezer?
The cold temperature in the freezer will cause the air molecules inside the balloon to contract, making the balloon shrink in size. If the balloon gets cold enough, the rubber may become brittle and more prone to popping.
Will the lack of support from boxers cause the testicles to hang down lower?
No. Testicle length is determined by how comfortable they are. Usually in cold air or water, they will shrink up and get tight. In heat, they loosen up and hand lower.
