H of 10 is 43 degrees Celsius. So this is 43 right over here. And from that, we're going to subtract our initial temperature, our temperature at zero minutes, which is 66 degrees Celsius. We're gonna subtract 66 degrees Celsius. This gives us negative 23 degrees Celsius. So our change in temperature is negative 23 degrees, or our temperature has gone down 23 degrees Celsius over the course of the first 10 minutes. So that is part, that is part C right over there.
