A hot cup of coffee will cool down at a certain rate, but as the coffee cools, the rate at which it cools slows down. This is why a "lukewarm" cup of coffee cools down so slowly. Even though the warm cup of coffee is cooling down quicker at first, the lukewarm cup essentially has a "head start" on the way to room temperature.

What increases in water before it evaporates?

The temperature of water increases before it evaporates.


What happens when you throw boiling water in freezing air?

When you throw boiling water in freezing air, the water quickly evaporates and turns into tiny droplets or ice crystals. This happens because the extreme temperature difference causes the water to rapidly cool and freeze before it hits the ground.


Why does hot glue from a glue gun dry so fast?

Hot glue from a glue gun dries quickly because it cools down rapidly when exposed to air, causing it to harden in just a few seconds. The high temperature of the glue when it exits the gun allows it to bond surfaces quickly before it solidifies.


Why does the ambient temperature need to be measured before and after the?

You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.


What happens to the temperature before it starts to rain?

Before it starts to rain, the temperature may drop slightly due to the cooling effect of the rain clouds blocking sunlight. However, sometimes the temperature can remain warm and humid leading up to a rainstorm.

What temperature is lukewarm?

Just a little bit above cold, somewhere around body heat. Body heat is 98.6°F or 37.0°C. So lukewarm would fall roughly somewhere between 79 - 97 °F or 26 - 36°C.

How long can water sit out at room temperature before it is no longer drinkable?

At room temperature, bacteria (which are everywhere, even in your water) multiply very rapidly, so be wary of water that's been sitting for more than a few hours, particularly if uncovered.

You run it until the engine reaches normal operating temperature on the temperature gauge this way the oils viscosity will be correct. on colder days you need to run it longer.


How long can food sit out covered before it becomes unsafe to eat?

Food should not sit out at room temperature for more than 2 hours before it becomes unsafe to eat. After this time, bacteria can grow rapidly and cause foodborne illness.
