What else can I help you with?
What should be done with any unused or used chemical once it has been taken from the original container?
An unused portion of a chemical taken out of its container should be properly disposed of. The original container has identification information and warnings. Chemical that been poured out may become contaminated so should not be poured back.
What do you notice about its temperature during boiling?
When a liquid is boiling the temperature stays constant. This is because the heat energy you are adding is being taken away with the vapour being produced.
Does the volume of water affect the time taken for the water to reach it's boiling point Why?
Yes, the volume of water can affect the time taken for it to reach its boiling point. A larger volume of water will generally take longer to reach its boiling point compared to a smaller volume, as more energy is required to heat up a larger amount of water.
How does pure water increase the boiling point?
Pure water does not increase - or in any other way affect - the boiling teperature of water becasue the latter is normally taken to be that for pure water!The question does not make sense. What type of water is it whose boiling temperature is meant to be increased by pure water? Impure water?In any case, pure water does not increase the boiling point of water but lowers it.
When a liquid sample is taken from sea level to a higher elevation what happens to the external pressure on the liquid and the boiling point of the liquid?
atmospheric pressure is lower and the boiling point is less
What might happened to the thermometer if you put in boiling water after taken out of freezer?
There will be a sudden change in temperature and it is likely that the thermometer may even break.
How a normal kettle works?
A normal kettle is a semi-closed metal container (with lid and spout) of water. When placed on a flame, the water inside the kettle heats up until it reaches boiling point. It is then ready to be taken off the flame and the boiling water poured into a teapot, or some other beverage, etc.
How long is breast milk good for after being taken out of the fridge?
Breast milk is safe to consume for up to 4 hours after being taken out of the fridge. After that, it should be discarded.
How long does breast milk last after being taken out of the fridge?
Breast milk can be safely stored at room temperature for up to 4 hours after being taken out of the fridge. After that, it should be discarded.
How long does breast milk last once taken out of the fridge?
Breast milk can be safely stored at room temperature for up to 4 hours after being taken out of the fridge. After that, it should be discarded.
How long should an egg be boiled if it is taken directly from the fridge?
An egg taken directly from the fridge should be boiled for about 7-9 minutes to achieve a firm yolk and fully cooked white.
How long can breast milk be safely used after being taken out of the fridge?
Breast milk can be safely used for up to 4 hours after being taken out of the fridge. After that, it should be discarded to prevent the risk of contamination.
Is the amount of heat taken from the contents of refrigerator greater than it gives out?
Due to the laws of thermodynamics, the heat produced (at the back of a fridge) is invariably greater than the amount of heat taken away (inside the fridge).
How long can breast milk be safely stored at room temperature after being taken out of the fridge?
Breast milk can be safely stored at room temperature for up to 4 hours after being taken out of the fridge. After that, it should be discarded.
How could you see a bottle taken from the fridge show that there is water vapour?
clouds
How does he amount of energy change during boiling?
During boiling, the amount of energy remains constant as the temperature of the substance stays the same until all of it has converted into vapor. Once boiling starts, the added heat energy is used to break the intermolecular bonds holding the liquid together, rather than increasing the temperature.
Where does the energy come from which makes the pipes at the back of a fridge warm?
The energy comes from the heat taken from the heat/energy inside of the refrigerator/fridge. A fridge takes heat energy from inside the fridge and dumps it outside the fridge into the the pipes on the back of the fridge and into the room.
