Due to specific heat of water it is used in a. radiator of car
b. hot water bag for pain relief
c. both a. and b.
d. thermometer

Answer 1

Answer:

If a radiator is too cool, it needs more hot water flowing through it, and if another is too hot, then the flow through it needs restricting. ... Then, starting with the radiator nearest the boiler, close the lockshield valve completely off (fully clockwise) and then open it a one-quarter turn

Explanation:

Boiler thermostat: this should be set at 65 degrees, to enable it to deliver water of 60 degrees (see above). While radiators will get hot quicker if the boiler thermostat is set at a higher temperature, the boiler may not condense, which will reduce its efficiency by 10-20%.

Answer 2

Answer: It will be both a and b.

Explanation: Because waters specific heat capacity is high.
