ThermodynamicsTemperature Problems

$$
\text { What is the temperature of the heated air at } 150^{\circ} \mathrm{C} \text { in }^{\circ} \mathrm{F} \text { and } \mathrm{R} ?
$$

$$
T(^{\circ}{F})=1.8 T(c^{\circ})+32=1.8(150)+32=302 \ ^{\circ} \mathrm{f}
$$

$$
T(R)=T(^{\circ}F)+460=302+460=762 R
$$

$$
\begin{array}{l}{\text { The temperature of a system rises by } 45^{\circ} \mathrm{C} \text { during a heating process. }} \\ {\text { Express this rise in temperature in kelvins. }}\end{array}
$$

$$
\Delta T(k)=\Delta T(^\circ{c})
$$

$$
45 k=45^{\circ} \mathrm{C}
$$

$$
\Delta { F: 10F }
$$

$$
\Delta T=\frac{10}{1.8}=5.6 \ ^\circ{c}
$$

$$
\Delta T=\frac{10}{1.8}=5.6 k
$$

$$
\Delta T=10 \ ^{\circ} F=10 R
$$
