What does heat do to friction?
Heat can increase the kinetic energy of molecules, which can lead to a reduction in friction between surfaces. However, excessive heat can also cause materials to expand, leading to increased friction. It is important to find a balance between temperature and friction to optimize performance.
How does friction heat affect the performance of mechanical systems?
Friction heat can negatively impact the performance of mechanical systems by causing parts to wear out faster, leading to increased energy consumption and reduced efficiency. Additionally, excessive friction heat can cause components to expand or warp, potentially leading to malfunctions or failures within the system.
What is the effect of friction force on plant?
Friction force can help plants anchor themselves to the soil and prevent them from being easily uprooted by external forces like wind or water flow. It also aids in the uptake of water and nutrients from the soil through the roots by providing a grip for the root hairs to push through the soil particles. However, excessive friction can restrict root growth and limit the plant's ability to expand its root system.
How does friction reduce the efficiency of machines?
Friction is cased by parts of the machine rubbing past one another. When this happens the parts tend to stick to each other which slows down the machine and heats up the parts. Thus the energy used to drive the machine is diverted from the purpose for which the machine was constructed and the machine becomes less efficient. To reduce friction and make the machine more efficient, lubricants (eg oil) are used to make sure that parts that come into contact can slide past one another more easily. -------------------------------------------------------------------------------- Friction causes machines to slow down, and heat up. effecting efficiency negatively first off excess causes a decrease in speed increase in wear on parts. Also friction causes heat which causes metals to expand. For optimal mechanical efficiency, friction is the enemy. ------------------------------------------------------------------------------------ Friction decreases efficiency. This is because when there is friction, heat is created. Therefore some energy is lost in the form of heat.
How do gun silencers work to reduce the noise of a gunshot?
Gun silencers work by trapping and slowing down the escaping gases from a gunshot, which reduces the noise produced. The silencer contains baffles that allow the gases to expand and cool before exiting the device, muffling the sound of the shot.
What prevents friction between the lungs and the ribs when breathing?
the flesh and padding muscles in between each
When there is no friction in space then how will blowed balloon expands?
The balloon will expand due to the pressure in its inside. This has nothing to do with friction.
Why did concord expand during flight?
Metal expands when heated, friction.
Do car tires expand in the summer?
Yes, the heat causes the air to expand in the tires. Conversely, the cold air in winter reduces tire pressure.

How does Yeast expand?
Yeast expands because in the heat, it eats and digests sugar, and then it produces carbon dioxide gas.
How does a man squeeze his penis into the vagina?
The vagina can expand a lot, it also produces a natural lubricant that eases intercoarse
If you dont eat can you belly get larger?
Yes. There is a condition where the stomach digests and produces gases, but since there is no or little food to digest, the stomach produces to much of the gases and the stomach will expand and distend as a result.
What is the purpose of an engine lubricant?
To keep the moving parts cool and lubricated so the metal does not expand (caused be friction and heat) and seize the engine.
Explain why do bus tires can greatly increase when traveling over along distance at high speed?
Vehicles ove forward because of friction between the tyres and the road. Friction causes heat so the tyres and the air inside them heat up. A confined gas (air) tries to expand when it is heated. Tyres will expand, when the air inside applies sufficient pressure.
How does friction heat affect the performance of mechanical systems?
Friction heat can negatively impact the performance of mechanical systems by causing parts to wear out faster, leading to increased energy consumption and reduced efficiency. Additionally, excessive friction heat can cause components to expand or warp, potentially leading to malfunctions or failures within the system.
What causes a sealed bag of vegetables to expand?
A sealed bag of vegetables can expand due to the buildup of gas produced by bacteria present inside the bag. This gas is produced as a result of the vegetables undergoing fermentation, which produces carbon dioxide as a byproduct. If the bag is not properly vented, the trapped gas can cause the bag to expand.
