The results of an experiment to stretch a spring are shown in Table 5.3. Use the results to plot a load- extension graph. On your graph, mark the limit of proportionality and state the value of the load at that point.

option number c is the right answer.

conservation of mass

mass before something happens = mass afterwards

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
