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 10Β°C and 20Β°C, there are 5 divisions. So each division measures: (20^β πΆβ10^β πΆ)/50=(10^β πΆ)/5=2^β πΆ Each division measures 2Β°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 10Β°C and 20Β°C, there are 10 divisions. So each division measures: (20^β πΆβ10^β πΆ)/10=(10^β πΆ)/10=1^β πΆ Each division measures 1Β°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 10Β°C and 20Β°C, there are 20 divisions. So each division measures: (20^β πΆβ10^β πΆ)/20=(10^β πΆ)/20=γ0.5γ^β πΆ Each division measures 0.5Β°C.
