Zero just gives you an arbitrary point on the number line to measure the other two points from. The fact that it happens to be the melting point of ice is irrelevant to this problem.
-89 is colder than -39
-89 is LEFT of -39 on our number line
-89 < -39
how much colder is and absolute value
-39 - (-89) = 50 degrees colder
I need help please.
Mercury is a metal that is liquid at room temperature. Its melting point of -39 degrees Celsius. The melting point of isopropyl alcohol is -89 Celsius.
(Part A) In the context of this problem, what does zero mean ?
(I think it just tells if the liquid will be solid or liquid )
(Part B) which of the temperature is colder -39 Celsius or negative 89 Celsius? Write an inequality statement.
( think its: -39 < -89)
(Part c) how much colder is a lower melting point?
(-59 is melting point)
