A cold-storage cabinet is at −18 ∘C-18\,^{\circ}\text{C}−18∘C. Use T=θ+273T=\theta+273T=θ+273, where T T\,T is the temperature in kelvin and θ \theta\,θ is the temperature in degrees Celsius.
Calculate the temperature of the cabinet in kelvin.
The cabinet's temperature rises by 8 ∘C8\,^{\circ}\text{C}8∘C. State the temperature rise in kelvin.
