Final answer:
The freezing point of Liquid B is 113.7°C.
Step-by-step explanation:
The freezing point of a substance is the same as its melting point. At this temperature, the solid and liquid states are in equilibrium.
Given that Liquid A has a freezing point of -62.1°C and its temperature is currently 25.8°C, we can calculate the temperature difference between the current temperature and the freezing point of Liquid A:
Temperature difference = freezing point - current temperature = -62.1°C - 25.8°C = -87.9°C
Since we want to find the freezing point of Liquid B, which has the same temperature as Liquid A, we need to subtract the calculated temperature difference from the current temperature of Liquid B:
Freezing point of Liquid B = current temperature of Liquid B - temperature difference = 25.8°C - (-87.9°C) = 25.8°C + 87.9°C = 113.7°C
