Answer: b)298 K converts to 24.9 °C, so the water would remain in its liquid state
Explanation: Kelvin is an absolute temperature scale, that means that 0K (zero Kelvin) is the lowest temperature possible and compare to Celsius scale the change of 1 degree is the same, but 0°C is the same as 273,1K
So, in order to convert Kelvin to Celsius you have to subtract 273,1
In this case, 298K - 273,1 = 24,9°C
This temperature is room temperature, so water is in liquid state.
