Why does air in a room rise when it gains thermal energy from a heater? (1 point)
Its molecules move around more quickly, so there is more space between them, reducing its mass
Its molecules move around more slowly, so there is more space between them, making it less dense than the air above it Warm air always rises.
O Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it
here are the answers to the quick check.
1: As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa.
2: Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it.
3: Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed.
4: Hot soup warms the bowl where it sits.
5: transfer of thermal energy through infrared waves
The correct answer is: Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it. When air is heated, its molecules gain thermal energy and move faster, causing them to spread out and occupy more space. This makes the air less dense than the surrounding cooler air, causing it to rise upward due to the force of buoyancy.
hello kittys answers are 100% correct thx
You're welcome! I'm glad I was able to help. If you have any more questions, feel free to ask!
Warm air always rises because it secretly dreams of becoming a hot air balloon and soaring through the skies. Its molecules get all excited, start moving around like crazy, and create more space between them. This makes the air less dense than the air above it, so it naturally floats up where it can show off its newfound hotness.
The correct answer is: its molecules move around more quickly, so there is more space between them, making it less dense than the air above it.
When air gains thermal energy from a heater, its molecules start moving faster and colliding with each other more vigorously. This increase in kinetic energy causes the molecules to spread out and occupy more space, which leads to a decrease in air density.
Less dense air is lighter than the surrounding air, so it experiences a buoyant force that pushes it upward. This buoyant force is a result of the density difference between the warmed air and the cooler air around it.
The concept behind warm air rising is known as convection. It occurs because warm air expands and becomes less dense compared to its cooler surroundings. This density difference causes the warm air to rise while cooler air sinks to take its place.
To summarize, the air in a room rises when it gains thermal energy from a heater because its molecules move around more quickly, leading to an increase in the spacing between them and a decrease in density compared to the surrounding air.
6: Conduction is the transfer of thermal energy through direct contact of two materials.
7: Radiation is the transfer of thermal energy through electromagnetic waves.
8: Convection is the transfer of thermal energy through the movement of fluids or gases due to differences in temperature.
