Answer:
The controlled variable of an experiment is the one thing that stays the same in an experiment.
Explanation:
An example would be : if I have two pennies, both dunked in water, but than I change one to be dunked in vinegar, the one dunked in water still is the constant or the controlled variable.
Answer:0.0922 Fahrenheit per minute
Explanation: Temperature change in degree Fahrenheit from Celsius is given by multiplying the change in temperature in celsius by 1.8 and adding 32 to it. Now the temperature you added is in Fahrenheit. But the temperature change is for a day. To convert change in temperature per day to per minute divide the obtained answer in Fahrenheit by 24*60.
Thus,
change in temperature in Fahrenheit: (56*1.8)+32= 132.8 degree Fahrenheit
change in temperature per minute: (132.8)/(24*60)= 0.0922 degree Fahrenheit per minute
