On converting 25°C, 38°C and 66°C to kelvin scale, what is the correct sequence of temperature?
Understand the Problem
The question requires converting three Celsius temperatures (25°C, 38°C, and 66°C) to Kelvin and identifying the correct sequence of the converted temperatures. To convert from Celsius to Kelvin, you add 273.15 to the Celsius temperature.
Answer
(a) 298K, 311K And 339K
Answer for screen readers
(a) 298K, 311K And 339K
Steps to Solve
- Convert 25°C to Kelvin
To convert Celsius to Kelvin, we add 273.15 to the Celsius temperature. $25 + 273.15 = 298.15 \approx 298 K$
- Convert 38°C to Kelvin
Similarly, we add 273.15 to 38°C $38 + 273.15 = 311.15 \approx 311 K$
- Convert 66°C to Kelvin
Add 273.15 to 66°C $66 + 273.15 = 339.15 \approx 339 K$
- Identify the correct sequence
The converted temperatures are approximately 298 K, 311 K, and 339 K.
(a) 298K, 311K And 339K
More Information
The Kelvin scale is an absolute thermodynamic temperature scale that uses absolute zero as its null point. It is widely used in scientific measurements.
Tips
- Forgetting to add 273.15 to the Celsius temperature.
- Rounding errors during addition.
