The air temperature is -10 degree Celsius. With the wind blowing at a speed of 15 km/h, this temperate feels like -17 degrees Celsius. How many degrees does the temperature change because pf the wind chill?

Change = -17-(-10) = -17 + 10 = -7o C.

Change = -17 - (-10) = -17 + 10 = -7o C.

To determine the change in temperature due to wind chill, you need to find the difference between the actual temperature and the perceived temperature caused by the wind.

In this case, the actual temperature is -10 degrees Celsius, and the perceived temperature due to wind chill is -17 degrees Celsius. To find the change in temperature, you subtract the perceived temperature from the actual temperature:

Change in temperature = Actual temperature - Perceived temperature

Change in temperature = (-10) - (-17)
Change in temperature = -10 + 17
Change in temperature = 7 degrees Celsius

Therefore, the change in temperature due to wind chill is 7 degrees Celsius.
