What else can I help you with?
What will happen if you put hot water on a fire in a pan?
If you pour hot water on a fire in a pan, the water can evaporate rapidly and turn into steam, potentially causing the fire to flare up or spread. It's generally not recommended to use water on a grease fire as it can make the situation worse.
What change in the water level occurs when you hold Erlenmeyer flask over a candle in a pan of water?
When you hold an Erlenmeyer flask over a candle in a pan of water, the water inside the flask heats up and expands, causing the water level in the flask to rise. This is due to the expansion of the water molecules as they gain thermal energy from the heat source.
Should I use soapy water in a cast iron pan?
Not a good idea. Cast iron is greased and "seasoned" by being heated, which seals pores in the iron pan. Using soapy water strips that away- it will rust, food will stick to it. Most can be wiped clean. If it does get the soapy water treatment, renew the seasoning by wiping it with oil, heating it in the oven and let it cool.
What is a chip-pan fire?
The Stages of a chip pan fire 1. Oil gets so hot that it catches fire all by itself 2. Water is poured into the burning chip pan 3. Water is denser than oil, so it sinks to the bottom of the chip pan (shown in red). As the water touches the bottom, it is heated above its boiling point and instantly vaporizes. 4. The water vapour expands rapidly, ejecting a fireball of burning oil out of the chip pan and into the air where its surface area increases greatly and combustion proceeds much faster
What property is used to separate gold from sand when they are swirled in a pan filled with water?
Density. Gold has an extremely high density relative to the rest of the sand in the pan and will therefore fall to the bottom as one swirls the pan around. The water is there to provide a means by which to circulate the dirt mixture and eliminate the "sand" (the sand gets suspended in the water and spills over the sides of the pan as it is swirled). And that's pretty much panning for gold.
Is a pan over a flame radiation or conduction?
Both the flame heating the pan and the pan heating the water are examples of conduction. Convection is when the molecules of water heat other molecules of water.
How do you boil water on an open fire?
By putting the water in a pan/pot and then hold the pan/pot over the fire until hot :)
How do you make a grease fire?
Throw water onto over-hot chip pan.
What is the best way to keep pudding from burning?
Lower flame and keep stirring or put preparation pan in another pan of water so it is not directly over the heat source.
How do get hard caramel out of a pan?
Soak in hot water
What direction will heat flow if cold water is added to a hot pan?
Water droplets will start evaporating on contacting the pan bottom, and they will tend to "dance" on the produced steam.
What melts faster ice in hot water or ice in a frying pan?
Ice melts faster in hot water than in a frying pan. When ice is placed in a hot frying pan, it forms a layer of steam which it floats upon, that insulates it, to some degree, from the frying pan. Thermal conduction is better when it is immersed in hot water.
Why are pans placed over a flame and not on the side of the flame?
Pans are placed over a flame and not on the side of the flame, because it is an energy transfer by direct contact called conduction. And as you can see, pans are usually made of metals, wherein metals are a good conductor of heat unlike wood, which is a poor conductor of heat.
What type of graph should you use if you want to record the temperature if a hot water in a pan?
A line graph would be suitable for recording the temperature of hot water in a pan over time. This type of graph can effectively show how the temperature changes at different time intervals.
What are the potential risks associated with having water in a hot water heater pan?
Having water in a hot water heater pan can pose risks such as potential leaks, corrosion of the water heater, and the growth of mold or bacteria due to standing water.
When you boil water to make pasta hot water from the bottom of the pan carried thermal energy to water molecules at the top of the pan. this is an example of?
convection
