A hot piece of brass (c = 380 J/kg˚C) is placed in water (c = 4180 J/kg˚C) to cool. The final temperature of the “mixture” will be closer to the initial temperature of which substance? Explain.

Given :

A hot piece of brass (c = 380 J/kg˚C) is placed in water (c = 4180 J/kg˚C) to cool.

To Find :

The final temperature of the “mixture” will be closer to the initial temperature of which substance.

Solution :

We know, change in temperature is inversely proportional to specific heat of the material.

In the given case specific heat of water is much greater than specific heat of brass.

So, change in temperature will be much in brass as compared to water.

Therefore, final temperature of mixture will be closer to the initial temperature of water.

Hence, this is the required solution.

the body's situation won't change the forces are equal opposit and on the same body

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
