The table shows the mass and melting point of some substances.

Question

Melting Point of Substances
Mass
(kg) Melting Point of Tin
(°C) Melting Point of Lead
(°C)
1 W Y
2 232 327

Part 1: What will be the values of W and Y for 1 kg of each substance?

Part 2: Explain your answer for Part 1.

Answer 1

Part 1: The values of W and Y for 1 kg of each substance are as follows:

For Tin:
W = 1 kg
Y = 232 °C

For Lead:
W = 1 kg
Y = 327 °C

Part 2: The values for W and Y are the same for each substance regardless of their mass. This is because the question asks for the values for 1 kg of each substance specifically. The mass of the substance does not change the values of W and Y.
