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.
The temperature of water increases before it evaporates.
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.
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.
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.
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.
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.
The right temperature must be at least 70 to 90 degrees
One notch before the halfway point.
Just about the same as your body temperature.
I swam rapidly trying to get to the finish line before my oppenent did. RAPIDLY MEANS VERY FAST
both correct in past or present.
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.
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.
no, its not a correct sentence. its have you taken the test before.
The correct sentence is the following: "What were you doing from before?"
It can be the heating block, which only needs to be replaced before you start getting warm air again.
