by boiling
convection currents an example is a heat radiator...it radiates heat which warms the air. the air rises as its heated and cooler air takes its place then being heated by the radiator...this continues until the room is heated and so is a pot is on a stove and the water is boiling and the cold water is at the top and it goes to the bottom
which diagram correctly indicates why convection currents form in water when water is heated
water vapor, mist, steam
Steam?
Only one liquid expands when heated and thats water the most common liquid.
The heat energy from the stove, which in turn comes from the burning of the chemical energy in the gas that is burning, or from the electrical energy, depending on the type of stove.
Convection: Hot water at the bottom rises, displacing cooler water, which then heats up and rises, creating a circulation that evenly distributes heat in the saucepan. Conduction: Heat is transferred directly from the stove to the saucepan, warming the metal of the saucepan which then transfers heat to the water in contact with it. Radiation: Heat from the stove is emitted as electromagnetic waves, which are absorbed by the saucepan and water, causing the molecules to vibrate and raise the temperature.
When water is heated on a stove, thermal energy is transferred to the water. This causes the water molecules to move faster and increase in temperature.
The boiling point of water at sea level is 100 degrees Celsius (212 degrees Fahrenheit). When heated on a gas stove, the water will reach its boiling point and start to boil, forming bubbles and producing steam.
boil the money in a saucepan full of water on the stove
it would be faster
Kettle. Or you could use a saucepan over the stove if you've not got one.
To boil or to blanch before refreshing
The water in the pot is usually heated using a heat source, such as a stove or induction cooktop. The heat from the source is transferred to the pot, which then heats up the water inside.
Conduction is the heat transfer between the saucepan and the water through direct contact, convection is the transfer of heat through the movement of the water molecules due to the temperature difference, and radiation is the heat transfer from the stove to the saucepan through electromagnetic waves. These principles work together to heat the water in the saucepan evenly.
Pot with water in it. Over a fire or on a wood heated stove.
When water is boiled on a stove, heat energy from the stove is transferred to the water. This heat energy increases the temperature of the water molecules, causing them to move faster and eventually reach a state of boiling where they turn into water vapor.
