Question

A thermometer reading 5 degrees celsius is brought into a room with a constant temperature of 35 degrees celsius.

a.) If the thermometer reads 15 degrees celsius after 3 minutes, what will it read after being in the room for 5 minutes? For 10 minutes?
b) Graph the relation between temperature and time. Use TRACE to verify that your answers are correct

Answer 1

If it starts at 5 degrees celsius and raises to 15 degrees celsius in 3 minutes it increases by about 3 1/3 every minute.
times that by 5 and you get 16 2/3. times that by 10 and you get 33 1/3
