because he is cold and the water was very hot. and he was not able to go
When the flask is immersed into hot water, the ink molecules gain thermal energy causing them to move more rapidly. This increased movement disrupts the intermolecular forces holding the ink together, making it less dense and causing it to rise up in the flask.
so as to keep the flask hot hereby keeping the hot water inside the flask hot.
Thermos flask or vacuum flask.
HOT rises COLD sinks
Warm, not hot, water will activate yeast causing them to produce carbon dioxide which causes breads to rise
Its because there are contact points between the inner part of the flask and the outer part, which allows some thermal conductivity to occur.
It is overheating, it should be at least half immersed in water to keep cool.
Yes, you can.
A Thermos/vacuum flask is probably the best for small volumes of hot water (1 - 2 pints) After that any receptacle that is well insulated will maintain the temperature for a limited time.
a flask is where people pour hot drinks and take it out with them. the flask ensures that the drink remains hot for several hours so someone may take it for a picnic, prepare tea at 9 in the morning, and at 3 in the afternoon the tea is still hot.
So the steam can rise from the boiler to the hot water tank storage
Thermos Flask is a container that is used to prolong the temperature of a liquid. If a liquid it is hot,the thermos flask will work to make it stay hot longer. The heat will have no way to escape the flask which means the heat will stat longer, causing the liquid to stay hot longer.
