Compare the temperature of water as ice begins to form with the temperature of ice as it begins to melt

1 answer:

3 0

They are the same temperature.

If you have 1 gram of ice at zero degrees C, you have to pump 334 joules
of heat energy into it in order to<em> just change it from solid to liquid</em> at the <em>same temperature. </em>

This is one of the highest figures known for any substance, and that's why
a piece of ice does such a good job cooling your drink.

How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet? A. 2,260.8 cubic feet B. 13,5

MakcuM [25]

Answer:

Volume, V = 13564.8 cubic feet

Explanation:

It is given that,

Radius of the cylindrical tank, r = 12 feet

Height of the tank, h = 30 feet

We need to find the water that can be held by a cylindrical tank i.e. we need to find the volume of the tank. It is given by :

$V=\pi\times r^2\times h$

$V=3.14\times (12)^2\times 30$

V = 13564.8 cubic feet

So, the water held by the tank is 13564.8 cubic feet. Hence, this is the required solution.
