Answer 2

1. An iron ball at 50 °C is dropped in a mug containing water at 50 °C. The heat will :  (c) not flow

Heat flows from a body of higher temperature to a body of lower temperature. Here the temperature of both the objects is same. So, heat will not flow from one object to other or there will not be any change in the temperature of both the two objects.

2. What is the temperature of boiling water : (a) 212 °F

The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit at 1 atmosphere of pressure

3. Conduction is the mode of heat transfer in : (a) solids

Conduction is a process in which heat is transferred from the hotter part to the colder part in a body without involving any actual movement of the molecules of the body.
