The specific heat(c) of copper is 0.39 J/g °C. What is the temperature change(∆t) when 200 Joules of heat(Q) is added to 10 grams?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Which configuration would produce an electric current? a) rotate a coil of copper wire between two magnets. b) connect a wire between a copper and zinc strip sitting in a beaker of water. c) connect a wire to the (+) positive end of a battery and the other end to a light bulb. d) connect a wire to the negative end of a battery and the other end to a light bulb.

In a system, when potential energy decreases, then entropy also decreases. true false
