Maximum density of $H_2O$ is at temperature

The phenomenon of superconductivity is observed at a temperature of $95 \ K$. The corresponding temperature on the Fahrenheit scale is ...... $^\circ F$.

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 $^{\circ}C$)

If the temperature of a body increases by $30^{\circ}C$ on the Celsius scale,then the increase in temperature on the Fahrenheit scale is .... $^oF$.

The absolute zero temperature on the Fahrenheit scale is ........ $^\circ F$.

Give the name of the instrument that measures temperature. Write the freezing and boiling points of water in $^oC$,$^oF$,and $K$.
