What evidence in the pie chart shows that incomplete combustion of petrol has

answer: your mm

explanation:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
