Question

Chapter 14, Problem 1CQ

To determine

The direction of heat flow.

Expert Solution & Answer

Answer to Problem 1CQ

The direction of heat flow will be from hotter to colder object.

Explanation of Solution

The heat flow direction does not depend on the position of the objects. Gravity have no effect on the direction of the heat flow. The heat flow only depends on the temperature of the neighbouring objects.

The heat will always flow from the hotter object to the colder object. When two objects of different temperature are kept in thermal contact, the colder object will get hotter and the hotter object will get colder because of the heat transfer. The heat transfer will occur till thermal equilibrium is attained.

A block of mass m₁ = 10.0 kg is connected to a block of mass m₂ 34.0 kg by a massless string that passes over a light, frictionless pulley. The 34.0-kg block is connected to a spring that has negligible mass and a force constant of k = 200 N/m as shown in the figure below. The spring is unstretched when the system is as shown in the figure, and the incline is frictionless. The 10.0-kg block is pulled a distance h = 22.0 cm down the incline of angle = 40.0° and released from rest. Find the speed of each block when the spring is again unstretched. Vm1 × 1.32 Vm2 = 1.32 × m/s m/s

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to support any additional load. Consider a leaf spring constant of 5.45 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y = 0.500 m. Truck body Dyo Axle (a) What is the compression of the leaf spring for a load of 4.90 × 105 N? m (b) How much work is done compressing the springs? ]

Answer to Problem 1CQ

The direction of heat flow will be from hotter to colder object.

Explanation of Solution

The heat flow direction does not depend on the position of the objects. Gravity have no effect on the direction of the heat flow. The heat flow only depends on the temperature of the neighbouring objects.

The heat will always flow from the hotter object to the colder object. When two objects of different temperature are kept in thermal contact, the colder object will get hotter and the hotter object will get colder because of the heat transfer. The heat transfer will occur till thermal equilibrium is attained.
