The temperature of a solution in a science experiment is -4.3°c. mark wants to raise
the temperature so that it is positive.

part a
give an example of a number of degrees celsius by which mark could raise the
temperature.

part b
write an equation to represent the situation.

part c
draw a number line and use arrows to represent the equation you wrote in part b

put several heating devices (such as heaters) and let them have use at maximum temperature for several minutes (or hours if you want it really hot)

Step-by-step explanation: the heaters are available to bring warmth to the room by collecting the air particles in the room and heating them up then releasing it causing it to pile up amounts and heating up the entire room.
