A steel Railway track in kaduna has a length of 27 metres when temperature is 35° Celsius a. what is the length on the Third Day when the temperature is 44 degree celsius
B. suppose the track is held firmly to the ground so that it cant expand 10 as stress result in the track due to the temperature change take young modulus of Steel as 2.0 x 10 1m square and coefficient of linear expansion of Steel as 1.1×10-³⁰c

9. an object is moved from the outdoors, which is at a temperature of 100 ºf, to a room at a temperature of 70 º f. what happens to the object when it’s placed in the room with a lower temperature? the object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. the object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs. the object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same. the object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
