Answer:

(a) 2.1°C per minute

(b) 1.9°C per minute

Step-by-step explanation:

(a)

  • O min = 222.6°C [Given]

  • 10 min = 205.6°C [Given]

  • Difference of time = 10 min

  • Difference of Celcius = (222.6 - 205.6)°C = 21.0°C

  • [tex] \bf \frac{celcius}{time} = \frac{21.0}{10} = 2.1°C\: per\: minute [/tex]

(b)

  • 30 min = 157.6°C [Given]

  • 50 min = 119.6°C [Given]

  • Difference of time = 20 min

  • Difference of Celcius = (157.6 - 119.6)°C = 38.0°C

  • [tex] \bf \frac{celcius}{time} = \frac{38.0}{20} = 1.9°C \:per \:minute [/tex]
