The temperature of an object is 250 K. Find its temperature in centigrade. Help me with this assignment.
The Correct Answer and Explanation is:
To convert the temperature from Kelvin to Celsius (Centigrade), you can use the following formula: T(°C)=T(K)−273.15T(°C) = T(K) – 273.15T(°C)=T(K)−273.15
Where:
- T(°C)T(°C)T(°C) is the temperature in Celsius,
- T(K)T(K)T(K) is the temperature in Kelvin.
Given:
- Temperature in Kelvin = 250 K
Calculation:
T(°C)=250K−273.15=−23.15°CT(°C) = 250 K – 273.15 = -23.15°CT(°C)=250K−273.15=−23.15°C
Final Answer:
The temperature of the object is -23.15°C.
Explanation:
The Kelvin scale is an absolute temperature scale where zero Kelvin (0 K) is the absolute lowest possible temperature, also known as absolute zero, where all molecular motion stops. In the Celsius scale, 0°C is the freezing point of water and 100°C is the boiling point at 1 atmosphere of pressure. To convert from Kelvin to Celsius, you subtract 273.15 because 0 K is equivalent to -273.15°C.
Thus, when the temperature is 250 K, it is 23.15 degrees below freezing on the Celsius scale. This tells you that the object is at a very cold temperature, below the freezing point of water.
