A temp change of 20 degrees C corresponds to a temp change of
68degrees F
i got this one wrong? what's up with that?
68degrees F

so that 212-32= 190 degrees F spans as much as 100 degrees C so each degree C corresponds to 190/100= 1.9 degrees F.
A change of 20 degrees C corresponds to a change of 20(1.9)= 38 degrees F.
(Or, you could have argued that 20 degrees C is 1/5 of the way from freezing to boiling and so corresponds to (212-32)/5= 190/5= 38 degrees F.
(Oh, by the way, a temperature of 20 degrees C is 70 degrees F, not 68. The general formula is F= 1.9C+ 32.
A temperature change of 20 degrees C refers to a difference of 20 degrees Celsius between the initial and final temperature of a system. It can represent an increase or decrease in temperature depending on the context.
A temperature change of 20 degrees C can be measured using a thermometer, which is a device that measures the temperature of a system. The change can be calculated by subtracting the initial temperature from the final temperature.
There are several factors that can cause a temperature change of 20 degrees C, including heat transfer, chemical reactions, and changes in atmospheric pressure. Human activities, such as burning fossil fuels, can also contribute to temperature changes.
The significance of a temperature change of 20 degrees C depends on the context. In some cases, it may represent a small change, while in others it may have a significant impact on the system. For example, a 20-degree increase in body temperature can indicate a fever, which is considered significant.
A temperature change of 20 degrees C can have varying effects on living organisms. Some organisms have adapted to survive in extreme temperature changes, while others may be more sensitive and can experience negative impacts on their health and survival. Climate change, which involves significant temperature changes, can also have widespread effects on ecosystems and the organisms living within them.
