Temperature change- algebra 1
The temperature changes of two calorimeters were monitored and recorded Calorimeter A contained 250 milliliters of water with an initial water temperature of 120°F After 10 minutes, the temperature of the water in Calorimeter A steadily decreased to 100°F Calorimeter B contained the same amount of water as Calorimeter A but its initial water temperature was 20°F The rate of the increase in water temperature in Calorimeter B was 3°F per minute.
A) Write a system of linear equations for the temperature, T °F, of the
water in Calorimeters A and B in terms of the time, t minutes.
B) After how many minutes will the temperature of the water in the two
calorimeters be the same? How do you know?
