Question 1.
Convert the following temperature in the Fahrenheit Scale.
(a) 20°C
Solution:
20°C
Step 1: Multiply 20 by \(\frac{9}{5}\)
20 × \(\frac{9}{5}\) = 36
Step 2: Add 32 to 36
32 + 36 = 68
So, 20°C = 68°F
(b) 45°C
Solution:
45°C
Step 1: Multiply 45 by \(\frac{9}{5}\)
45 × \(\frac{9}{5}\) = 81
Step 2: Add 32 to 81
32 + 81 = 113
So, 45°C = 113°F
(c) 75°C
Solution:
75°C
Step 1: Multiply 75 by \(\frac{9}{5}\)
75 × \(\frac{9}{5}\) = 135
Step 2: Add 32 to 135
32 + 135 = 167
So, 75°C = 167°F
(d) 100°C
Solution:
100°C
Step 1: Multiply 100 by \(\frac{9}{5}\)
100 × \(\frac{9}{5}\) = 180
Step 2: Add 32 to 180
32 + 180 = 212
So, 100°C = 212°F
(e) 85°C
Solution:
85°C
Step 1: Multiply 85 by \(\frac{9}{5}\)
85 × \(\frac{9}{5}\) = 153
Step 2: Add 32 to 153
32 + 153 = 185
So, 85°C = 185°F
(f) 10°C
Solution:
10°C
Step 1: Multiply 10 by \(\frac{9}{5}\)
10 × \(\frac{9}{5}\) = 18
Step 2: Add 32 to 18
32 + 18 = 50
So, 10°C = 50°F
