What else can I help you with?
What is true A warm air is less dense than cool air B warm air is as dense as cool air. C warm air has no density. D warm air is denser than cool air?
A warm air is less dense than cool air (Option A). When air is heated, the air molecules become more energetic and spread out, decreasing its density. Conversely, cool air has denser molecules as they move slower and are more tightly packed together.
Warm air and cold are what?
warm air and cold air are both different pressures and density's!!!!
How is cool air different from warm air?
Lower energy.
When warm air rises and cool air sinks what current is created?
When warm air rises and cool air sinks, a convection current is created. This is due to the difference in air density caused by temperature variations. Warm air is less dense and rises, while cool air is denser and sinks, creating a circular flow of air.
Does warm air rise because of density?
Yes..Low density rises. As the particle gain more kinetic energy from being heated the density decreases as the particles move further apart causing a lower density. This could then form a convenction current but that is a different topic!
In Figure 15-1 cool air is more dense and forces up air.?
Yes, that's correct. Cool air is denser than warm air, so when cool air encounters warm air, it forces the warm air to rise due to differences in density. This process is known as convection, which plays a significant role in atmospheric circulation and weather patterns.
What makes the tendency for warm air to raise and cool air to sink?
Warm air is less dense than cool air because its molecules are moving faster and spread further apart. This reduced density causes warm air to rise, as it is lighter than the denser, cooler air around it. Conversely, cool air sinks because it is denser and heavier than the surrounding warm air.
How does convection happen?
Liquids and gasses tend to expand when heated, this lowers the density, thus warm "air" rises and cool air falls.
Why does cool air sink and warm air rises?
Because warm air is less dense then cool air.
Density of the air is greater when?
The density of air is greater at lower temperatures and higher pressures. This is because the molecules are closer together in a given volume, leading to higher density. Cool, dense air sinks while warm, less dense air rises.
Is warm air above or below cool air?
Warm air is typically found above cool air due to the process of convection, where warm air rises and cool air sinks. This is why the upper atmosphere is warmer than the lower atmosphere in most cases.
Is warm air dense?
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.
