Question

If the temperature of a patient is 40°C then what will be his temperature on Fahrenheit Scale?
1. 104°F
2. 98°F
3. 108°F
4. 106°F

Answer 1

Correct Answer - Option 1 : 104°F

The correct answer is 104°F.

• If the temperature of a patient is 40°C then his temperature on the Fahrenheit Scale will be 104°F.

• Given, Temperature in Celcius = 40^oC
• According to the formula,  \({C \over 100} ={{F-32}\over180}\)
• \({40 \over 100} ={{F-32}\over180}\)
• F = 72 + 32 = 104^oF.

• Temperature:
  • Temperature is that physical cause that decides the direction of flow of heat from one body to another body.
  • Heat energy always flows from the body at a higher temperature to the body at a lower temperature.
  • The normal temperature of a human body is 37°C or 98.4 °F.
  • The triple point is the state at which all the three states of matter co-exist.
  • The triple point of water is 273.16 K.
  • The device which measures the temperature of a body is called a thermometer.
  • The inter-conversion relation for Celsius, Fahrenheit, and Reumer scale is:
    • \({C \over 5} ={{F-32}\over9}={R\over4}\)
