Question 4 (1 point)
The diagram below shows two substances, A and B, which are at different temperatures.
What will happen when substance A is dropped into substance B?
a
Substance A and B will eventually reach the same temperature.
b
Substance A will get even warmer as heat flows into it from substance B.
c
Substance A and B will exchange heat, and they both will reach 25°C.
d
Substance A and B will exchange heat, and they both will reach 50°C.
a
Substance A and B will eventually reach the same temperature.
To determine what will happen when substance A is dropped into substance B, we need to consider the concept of heat transfer and the principles of thermodynamics.
When substances at different temperatures come into contact with each other, heat transfer occurs between them until they reach a state of thermal equilibrium. This means that heat will flow from the hotter substance to the cooler substance until their temperatures are equal.
In this case, substance A is at a different temperature than substance B. Therefore, when substance A is dropped into substance B, heat will start flowing from the hotter substance (substance A) to the cooler substance (substance B). This is because heat naturally flows from higher temperature regions to lower temperature regions.
The correct answer is option a: Substance A and B will eventually reach the same temperature as heat flows from substance A to substance B.
