Final answer:
When a metal block with a lower temperature is placed in a bowl of water, heat will be transferred from the water to the block until they reach the same temperature.
Step-by-step explanation:
When the metal block with a temperature of 30 Celsius is placed inside a bowl of water, heat will flow from the metal block to the water until they reach thermal equilibrium. Since the temperature of the metal block is lower than the water, heat will be transferred from the water to the block. As a result, the temperature of the metal block will increase while the temperature of the water will decrease.
This transfer of heat occurs due to the concept of thermal equilibrium, where objects at different temperatures tend to move towards the same temperature. The rate of heat transfer between two objects can be determined using the equation Q = mc∆T, where Q is the heat transferred, m is the mass of the object, c is the specific heat capacity, and ∆T is the change in temperature.
In this case, the metal block will absorb heat from the water, causing its temperature to increase. The water will lose heat to the metal block, resulting in a decrease in its temperature. Eventually, both the metal block and the water will reach the same final temperature.
