What is the difference between mass vs weight?

• Mass remains constant in any location while weight doesn’t

• Weight remains constant in any location while mass doesn’t

• Mass is greater than weight

• Weight is greater than mass

Steel has a melting point of 1510 degrees Celsius. If all items would be placed into a big enough oven and the temperature increased to 1510 degrees, which item would melt first?

• The nail because its smaller

• The battle ship because it has the most area

• The silverware because its flat and it melts faster

• All would start melting at the same time because they are made up of the same substance

Making toast involves many energy transformations. As the electricity is forced through the wires, the wires begin to heat up and glow very hot. It is these hot loops of wire that cause the bread to brown making your toast. Describe the energy transformations

• Chemical energy-> Electrical energy-> Mechanical energy

• Thermal energy-> Mechanical energy-> Chemical energy

• Electrical energy-> Chemical energy-> Mechanical energy

• Electrical energy-> Thermal energy-> Chemical energy
