Kareem heats a beaker of water to a boil. Then he records that the water temperature decreases from 100°C to 19°C in 525 minutes. What was the change in temperature each minute? Enter your answer in the box. °C

Respuesta :

Answer:

Temperature of water in beaker decreased at rate of [tex]0.15428^{o} C[/tex] per minute.

Step-by-step explanation:

We are given:

[tex]\text{Initial temperature}=100^{o} C[/tex]

[tex]\text{Temperature after 525 minutes}=19^{o} C[/tex]

[tex]\text{ Change in temperature of water}=(100-19)^{o} C=81^{o} C[/tex]

Now we will divide change of temperature by 525 minutes to find change in temperature of water per minute.

[tex]\text{ Change in temperature of water per minute}=\frac{81^{o} C}{525\text{ minutes}}[/tex]

[tex]\text{ Change in temperature of water per minute}=\frac{0.15428^{o} C}{\text{ minute}}[/tex]

Therefore, temperature of water decreased at rate of [tex]0.15428^{o} C[/tex] per minute.
