Hot air has
Less atmospheric pressure, in other words the air is thinner. ... Cold air is heavier than hot air *at the same pressure*
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Yes, warm air masses are lighter than cold air masses because warm air is less dense. As a result, warm air tends to rise while cold air sinks. This buoyancy difference plays a significant role in the movement of air masses in the atmosphere.
Warm air is less dense than cold air because the molecules in warm air have more energy and are more spread out, resulting in lower density. Cold air is denser because the molecules are closer together and moving slower.
No, warm air is less dense than cold air because the molecules in warm air have more energy and are spread out more, resulting in lower density.
When cold air moves toward warm air, it pushes the warm air upward because cold air is denser and therefore heavier than warm air. This creates a lifting mechanism known as cold air advection, which can lead to the formation of clouds and precipitation.
in the winter months i found in any vehicle to use 5w-30 in the winter months being that it;s a thinner oil and run 10 w-40 in the summer being that it's thicker, cuz the thicker the oil is the longer it takes to warm up and start flowing than thinner oil does during the winter months, i made the mistake by putting the thicker oil in my truck during the winter when it really gets cold and it didnt want to start at all, i had to use a forced heater to unthaw it..
Hot paper cups are typically designed with a thicker material and a layer of insulation to keep hot drinks warm, while cold paper cups are usually thinner and do not have insulation to prevent condensation from forming on the outside.
Bad oil pump are stoped up oil pump pick-up screen. Worn out engine bearings. when the oil is cold it is thicker and as it heats up it gets thinner.
Warm water is little bit hotter than cold water. The temperature of warm water is higher than that of cold water
Warm oil is alot thinner than cold oil. If the light doesn't come on until the car is warm it means the pressure is less with the thinner oil.Make sure the sender is accurate,then look into causes of low pressure, (bad pump,worn bearings)
Cold air is more dense than warm air.

If it is cold water, than it is cold. if it is warm water, it is normal
To keep the oil warm. Cold oil is thicker (think 'higher viscosity') than warm oil, and, as a result, takes longer to circulate to areas that need it. Keep the oil warm, and it circulates more quickly on equipment start-up.
For UK diving you may still want to vary the thickness of your gear, depending on the water temperature, but for footwear, thicker is better than thinner as it will get a rougher time than most of your suit. I would say 3mm at least.
warmer than a cold front and colder than a cold front
Yes, cold air is typically drier than warm air because cold air has a lower capacity to hold moisture compared to warm air.
