Q10 of 32 Page 107

A solution is to be kept between 40°C and 45°C. What is the range of temperature in degree Fahrenheit, if the conversion formula is

Let temperature in Celsius be C and temperature in Fahrenheit be F


Given,


Solution should be kept between 40° C and 45°C


⇒ 40 < C < 45


Multiplying by , we get



Adding 32, we get



⇒ 104 < F < 113



Hence, temperature in Fahrenheit should be between 104° F and 113° F.

The water acidity in a pool is considered normal when the average pH reading of three daily measurements is between 8.2 and 8.5. If the first two pH readings are 8.48 and 8.35, find the range of pH value for the third reading that will result in the acidity level being normal.
