Question

following are the temperature- time graph obtained by 4 Students in this experiment which one is likely to be correct?

Answer 1

( a) is correct answer of questions

Answer 2

Temperature time graph can be of two types.

1) Of an increasing temperature with time.

2) Of a decreasing temperature with time.

The type 1 has a positive slope and of type 2 has a negative slope.

According to the choices given in the question we need a graph that demonstrates the second relationship.

The relationship between temperature and time is linear.

The graph that demonstrates this linear relationship is the last graph.

The correct choice is therefore D.
