Homework Statement



Comment on the statement 'Today the temperature is 40[tex]\circ[/tex]C and yesterday it was 20[tex]\circ[/tex]C so it is twice as hot today as it was yesterday.'

The Attempt at a Solution



i feel that it is wrong to say that, although i think a body at 40[tex]\circ[/tex]C is twice as hot as a body at 20[tex]\circ[/tex]C. i guess i'm missing something....

any hint? thnks

Try expressing the temperatures in other units (Fahrenheit, Kelvin).
