yeah cold water is denser than room temperature (warm) water.
Droughts are cold because air is a natural cool temperature.. in your house your temperature is normally a warm or average temperature... your body..being warm as your core body temperature, you feels droughts because the air is pushed through under your door cooling the air inside the room. It's only cold because the room is normally, nevertheless warm. Another example - if your room was freezing cold you would most probably not even feel the drought only because the room if more colder then the air behind the door. - droughts are a natural cold substance and humans core temperature does not match up to it as same with the temperature of the room. (This is my estimated answer..may need summering up)
yes
It is because your body can digest water faster than anything else. Room temperature water does not have to be cooled down or warmed up for the body to accept. If you drink cold water, your body ahs to warm it to body temperature before it can be distributed throughout the body.
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
cold water absorbs heat from the surroundings and revert to room temperature
It tastes better in a cold temperature.
Anything at room temperature is regarded neither cold nor hot. <><><><><> If the question meant "Is nitrogen solid, liquid, or gaseous at room temperature?", then the answer is gaseous.
The temperature suddenly dropped and the room got cold, very cold.
Aluminum is a metal and is solid at room temperature. Since being frozen is the state of matter that is solid, rather than liquid or gas, aluminum at room temperature can be said to be frozen. It does not fell cold, because room temperature is not cold for us. Aluminum melts when the temperature goes above 660 °C (1,220 °F) and freezes when the temperature is below that. It boils, and turns into a gas when the temperature is above 2,519 °C (4,566 °F).
Its when a metal can recrystallize and have grain growth at room temperature, and so can be cold worked but not be strain hardened at the same time- its rather useful.
Room temperature.
Methane is a gas at standard temperature and pressure, also at room temperature unless the room in question is very cold!
Cold light
"Cold fusion" refers to fusion at (or near) room temperature, rather than the millions of degrees that are normally required. This has not been achieved so far - at least, not to any significant degree.
Get a fan to make the room cold.
either the temperature of the room dropped or everyone in the room got quiet
