The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time. However fire tube boilers have a low cost.
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
Falls and then rises
They get the food and light it on fire and put it under a test tube of water. How much energy is in the food depends on how much the water has heated up
Can you make salt water stack on a tube?

It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.
they have an air tube which stick out of the water surface and they breathe by that tube
Water tube boilers are used in marine and stationary applications. A water tube boiler heats by water flowing through tubes and being heated by fire externally.
A test tube is filled with tap water (about 25oC). An ice block is placed in the test tube and is kept at the bottom of the test tube by means of a wire gauze. Next (without delaying too much since the ice block would melt completely!), the test tube is bent and the upper end of the test tube placed in a Bunsen flame. It is found that the water at the upper end boils before the ice block melts. This shows that water is a poor conductor of heat.
