all right let's look at the homework six problem number 25 right so Boyle's law is given so it's a pressure P over temperature T is equal to a constant K alright and then what we want to find is when the temperature is increasing at two kelvins per hour we want to know the rate of change of the pressure all right so let's do that at first we need to find the K value so here's the the clue here so here's a temperature when temperature is 300 and the pressure is 900 right so plug it in pressure is 900 over temperature is 300 which is obviously 3 so that is the K value alright so we know K all right so we have this equation P over T is equal to 3 all right and I don't like a fraction so I'm going to go ahead and multiply both sides by T so that the pressure P is equal to 3t all right so let's take the derivative so if you take the derivative of this with respect to T we got the rate of cha
