Question 6 (Page 138) Colour to show the red column on the drawings of thermometers (Fig. 7.7) as per the temperatures written below :Between 10°C and 20°C, there are 5 divisions. So each division measures: (20^∘ 𝐶−10^∘ 𝐶)/50=(10^∘ 𝐶)/5=2^∘ 𝐶 Each division measures 2°C. Question 6 (Page 138) Colour to show the red column on the drawings of thermometers (Fig. 7.7) as per the temperatures written below :Between 10°C and 20°C, there are 10 divisions. So each division measures: (20^∘ 𝐶−10^∘ 𝐶)/10=(10^∘ 𝐶)/10=1^∘ 𝐶 Each division measures 1°C. Question 6 (Page 138) Colour to show the red column on the drawings of thermometers (Fig. 7.7) as per the temperatures written below :Between 10°C and 20°C, there are 20 divisions. So each division measures: (20^∘ 𝐶−10^∘ 𝐶)/20=(10^∘ 𝐶)/20=〖0.5〗^∘ 𝐶 Each division measures 0.5°C.
