$A$ thermoelectric thermometer is based on:

The temperature of a body is measured both in ${ }^{\circ} C$ and ${ }^{\circ} F$. $A$ graph is plotted with ${ }^{\circ} F$ on the $X$-axis and ${ }^{\circ} C$ on the $Y$-axis. Then,the cosine of the angle between the graph and the $X$-axis is

Maximum density of $H_2O$ is at temperature

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

On a temperature scale $Y$,water freezes at $-160^{\circ} Y$ and boils at $-50^{\circ} Y$. On this $Y$ scale,a temperature of $340 \ K$ is (in $^{\circ} Y$)

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