Thermometer with marking W, X, Y and Z

Thermometer with marking W, X, Y and Z

In figure thermometer is shown. The top of the mercury thread in a mercury-in-glass thermometer reaches point X at 0 °C and point Z at 100°C.

Choices

Choice (4) Response
a.

point X

b.

point Z

c.

point Y

d.

point W

Answer

d.

Explanation

Here given that At point x is 0 °C

And at point Z is 100 °C

Now as we know that
