William Heathcote Solutions for Chapter: Transformation, Exercise 7: Exercise 7

The melting point of copper is $1,358 \mathrm{K}$. Express this temperature in degrees Celsius.

The surface temperature of Venus is $462°\mathrm{C}$. Express this temperature in kelvin.

A balloon contains $4,000 {\mathrm{cm}}^3$ of air at a pressure of $99 \mathrm{kPa}$. The weather changes and the pressure increases to $102 \mathrm{kPa}$. What is the new volume of the balloon? Given that the volume of a sphere is $\frac{4}{3}\pi r^3$, by how much has the balloon’s radius changed?

A glass bottle is filled with air at $20°\mathrm{C}$ and at a pressure of $100 \mathrm{kPa}$. It is then heated until the temperature is $80°\mathrm{C}$. What is the new pressure inside the bottle?
