Water is a bad Conductor. Note this point! When water at the bottom of the vessel gets heated first, it expands. So its density goes lower. But the comparatively cold water at the top would be with higher density and so they would come down allowing lower dense water to move up. This gets repeated and thus convection current gets produced.
What else can I help you with?
What is concept of convection current?
the rising of warm water and cold water sinking
How is humidity and convection connected?
By remembering the process of convection and convection current rainfall we can relate both. Land breeze and sea breeze are due to convection current and humidity also occur there due to this.
Is a campfire an example of a convection current?
Yes, a campfire is an example of a convection current. As the air closer to the fire heats up, it becomes less dense and rises while cooler, denser air moves in to replace it. This creates a circular flow of air known as convection.
What happens with underfloor heating if water gets on the floor?
Underfloor heating is used to help with controlling the temperature in the house with the convection heating method. If water get on the floor, the water will condensate into steam.
How does thermal energy from a radiator reach the other side of the room?
Hot air from a radiator reaches the other side of a room by convection current. Convection current is when hot water/ air rises, hot water/ air cools, cool water/ air sinks, cool water/ air warms and then the cycle starts over.
How convection happens?
Convection happens due to the transfer of heat by the motion of a heated fluid such as air or water.
What is concept of convection current?
the rising of warm water and cold water sinking
What are convenction current and what do they cause?
Convection currents are caused by uneven heating of bodies of water/air, resulting in a current as hotter air/water rises, and cooler air/water sinks. For example on a stove-top, when boiling water, the water at the bottom will warm first, being closest to the fire. Rising to the top, it will cool and sink to the bottom, creating a current. That is why covering a pot is more efficient- when the hot water rises to the top due to a convection current, it cannot lose as much heat.
Where convection can happen?
Convection can happen in fluids such as air and water, where differences in temperature cause the fluid to rise and fall in a circular motion. This process helps to distribute heat energy more effectively and can be observed in phenomena like ocean currents, boiling water, and atmospheric circulation.
Does convection heat a pan of water?
Yes, convection can heat a pan of water. As the water near the bottom of the pan absorbs heat, it becomes less dense and rises, creating a convection current that circulates the water and helps to distribute the heat evenly.
How do the positions of hot and cold water affect the speed of convection?
noting it works (in the science meaning; to cause a change) a lot.
What happens to warmed water next to a heater Give a reason?
The warmed water next to a heater rises due to decreased density, creating a convection current. This movement helps distribute heat more evenly throughout the water.
What is a convection loop?
basically the scientific fact that heat rises and cold temperatures sink. A convection loop happens in air and water.
What might cause convection currents in the hot spring?
Convection currents in a hot spring are typically caused by the heating of water at the surface by geothermal energy, making it less dense and causing it to rise. As it rises, cooler water replaces it at the surface and the cycle continues, creating a convection current. This process helps distribute heat throughout the hot spring.
Water being heated in a pan circulates because of?
convection - as the water near the heat source gets warmer, it becomes less dense and rises, creating a current that circulates the water in the pan.
What might cause convection current in spring?
I'm not sure but i think it's because the rock heats the water to over 200*c and keeps it under very high pressure
What is a example of a convection but not conduction?
An example of convection without conduction would be the boiling of water in a pot. As the water heats up at the bottom of the pot, the hotter water rises to the top and cooler water moves downward to replace it. This creates a convection current that circulates the water, heating it evenly throughout the pot.
