Which of the following figures represents the relation between Celsius $(C)$ and Fahrenheit $(F)$ temperatures?

What is absolute zero temperature?

Which of the curves in the figure represents the relation between Celsius and Fahrenheit temperatures?

The resistance of the platinum wire of a platinum resistance thermometer at the ice point is $5\; \Omega$ and at steam point is $5.39\; \Omega$. When the thermometer is inserted in a hot bath,the resistance of the platinum wire is $5.795\; \Omega$. Calculate the temperature of the bath in $^oC$. (in $^{\circ}C$)

The surface of the lake is at $2^{\circ}C$. Find the temperature of the bottom of the lake in $^{\circ}C$.

If the two temperatures on the Fahrenheit scale differ by $54^{\circ}\text{F}$, then the difference in temperature on the Celsius scale is (in $^{\circ}\text{C}$)
