Question

Take a cup of hot water/tea. Measure its temperature accurately with a thermometer. What will happen to the hot water/ tea if it is left in a room for, say, one hour? Measure the temperature at fixed intervals at fixed intervals of five minutes and record (your observations) in the given table. Using these readings , try to draw a temperature- time graph.​

Answer 1

ANSWER:

The hot water/tea is about $\bold{50^{\circ} \mathrm{C}}$ in the start. The room temperature is about $\bold{26^{\circ} \mathrm{C}}$. The temperature starts decreasing with the passage of time. The temperature of tea will be somewhat around $\bold{50^{\circ} \mathrm{C}-26^{\circ} \mathrm{C}}$. The temperature decreases  gradually with the passage of time.

EXPLANATION:

The graph drawn between time and temperature is a curve inward. The temperature goes down till the room temperature and then there is no loss of temperature.

The time is plotted on the x-axis and the y is placed on the y-axis.  The graph starts from the top of the y axis and ends at the lower level of it and also after covering some area.

The temperature-time graph is attached below.

Answer 2

Answer:

the temperature will measure the hot water simple
