If the temperature of ice cream increases from -10 Celsius to 30 Celsius what is the increase in temperature in units of Degrees Celsius and Kelvin?
I am confused on the wording of this but the formula for Kelvin is K=C+273.15
What do I input for C?? Do I put 40?
30 - (-10) = 30 + 10 = 40
Since you just add a constant to C to get K...
Then the difference should be 40 here too.
For C you would enter both -10 and 30 find K in each case and take the difference. As I said above, it should be 40.
To find the increase in temperature in units of degrees Celsius, you need to subtract the initial temperature from the final temperature.
The initial temperature of the ice cream is -10 degrees Celsius, and the final temperature is 30 degrees Celsius.
So, the increase in temperature in degrees Celsius can be calculated as:
30°C - (-10°C) = 40°C
Now, to convert this increase in temperature to Kelvin, you can use the formula K = °C + 273.15.
For this calculation, you need to use the increase in temperature in degrees Celsius, which is 40°C (as you found).
K = 40°C + 273.15
K = 313.15 K
Therefore, the increase in temperature is 40 degrees Celsius or 313.15 Kelvin.
