Water has the maximum specific heat capacity of any fluid.
The amount of heat that one gram of a material needs either absorb or lose in order to alter its temperature by a degree Celsius is known as specific heat. This equates to one caloric, or 4.184 Joules, for water.
<h3>High heat capacity: what is it?</h3>
- Consider the amount of time it takes for a pot to get warm to the touch on the stove as opposed to how long it takes for the water within to warm up.
- A substance with a high heat capacity may absorb a lot of heat before registering a change in temperature.
<h3>Why does water have the greatest ability to retain heat?</h3>
Although the hydrogen bonds in water are much too weak to be compared to intra - molecular bonds like covalently or ionic bonds, they are nevertheless strong enough to require a lot of energy to break. Water boils at 100°C for this reason.
Many people believe hydrogen bonding is the cause of water's high specific heat.

Answer:
m=1000kg
v=72km/h=20m/s
Work = different of kinetic energy
W= ½ mv ²
W= ½ ×1000×20×20= 400000J
also written as 4×10^5 J
thank you

Explanation:
If you push Force is just a fancy word for pushing or pulling.
transformer makes use of mutual induction for its operation in which change in magnetic field in one coil due to variation of current , induces voltage in the other coil. so changing magnetic field in the primary coil is very much needed for the transformer. Alternating current is a current which varies with time , hence it is suitable to produce changing magnetic field in the primary coil. on the other hand , the direct current remains constant all the time. hence can not produce a changing magnetic field. so DC current is not useful for transformers.
