On touching a lump of ice, we feel cold because some heat passes from our body to the ice

Text Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Concept of Heat Transfer:** - When we touch an object, heat can transfer between our body and that object. Heat always flows from a warmer object to a cooler one until thermal equilibrium is reached. 2. **Identifying the Objects:** - In this scenario, we have two objects: our body (which is warmer) and the lump of ice (which is cooler). 3. **Heat Transfer Occurs:** - When we touch the ice, heat from our body transfers to the ice. This is because our body temperature is higher than that of the ice. 4. **Effect of Heat Loss on Body Temperature:** - As heat leaves our body and goes into the ice, the overall heat content of our body decreases. This loss of heat results in a decrease in our body temperature. 5. **Perception of Cold:** - The decrease in body temperature is what we perceive as feeling cold. The more heat that is lost to the ice, the colder we feel. 6. **Conclusion:** - Therefore, the statement is true: we feel cold when touching ice because heat is transferred from our body to the ice, resulting in a decrease in our body temperature. ---
