The amount of heat needed to increase the temperature of a substance by
is given by
where m is the mass of the substance, Cs is its specific heat capacity and
is the increase of temperature.
If we re-arrange the formula, we get
And if we plug the data of the problem into the equation, we can find the specific heat capacity of the substance:
Answer:
C. Volume
Explanation:
it displaces an equal amount of water to the amount of space it occupies.
21. light changes its direction when travelling through a new medium because denser mediums have a higher angle of refraction.

Correct option is
C
3 cm
RI=apparent depthreal depth
Substituting, 34=apparentdepth12
Therefore, apparent depth=412×3=9
The height by which it appears to be raised is 12−9=3cm

A tank is filled with water to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again?
