      Electricity, magnetics and heat conduction are physical properties.

      mili is unit of measurement 1000 times smaller than it's main measurement. Main measurement for mass is gram, this means 1000 miligrams is 1 gram. So 2500mg is 2,5 g.

      Basic equation, if 300=C+273 then C=300-273.

      Lenght is in meters, Density in kg/m3 , mass in kg and volume in liters (1dm3).

  • Do your own homework, kid. You won't learn anything if you only get the answers. How do you expect to do well on the test if you don't know how to arrive at the correct answer?

      Common sense would dictate using your textbook to understand key concepts. Armed with this conceptual understanding, you could easily tackle these simple questions.

  • This is elementary school chemistry...
