To find what will be the room temperature

10

hours after the process begins

Present temperature

= 1 0^{\circ} C

After every hour temperature is lowered at the rate of

5^{\circ} C

Therefore, in

10

hours the temperature is lowered by,

= 5 \times 1 0^{\circ} C

= 5 0^{\circ} C

Temperature After 10 hours

= 4 0^{\circ} C - 5 0^{\circ} C

= - 1 0^{\circ} C
