A 10.0-m3 tank contains steam at 275°C and 15.0bar. The tank and its contents are cooled until the pressure drops to 1.8bar. Some of the steam condenses in the process. (a) How much heat was transferred from the tank? (b) What is the final temperature of the tank contents? (c) How much steam condensed (kg)?

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final

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) ! : )

What equation is used to calculate the weight of an object on a plant ?
