The specific heat of a solid Y is 11.5 cal/g°C. A sample of this solid at 135 K is heated to 260 K. The solid absorbs 7.90 kcals. What is the
sample of solid in grams?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
