Have you are burned something on the stove or in the oven? Do you know why things burn? It all has to do with temperature. Changes in matter are affected by temperature. For example, what if you place a cake in the oven and you leave it in too long? What do you think will happen? Thats right, it will probably burn. The same thing will happen if the oven setting is too high and you apply too much heat. In either case, heat has affected the rate of change in matter. Its probably obvious that when the temperature is increased a chemical change, like cooking, will occur faster. What about a physical change? Are physical changes affected by temperature? Most of us have seen steam rising off a wet road after a summer rainstorm. This happens because the road surface is very warm. The warm road and warm air temperature causes the water to evaporate quickly. The liquid water is turning into water vapor, but it is still water. The evaporation of water is a physical change. So yes, temperature affects the rate that physical change occurs.

What is causing cakes in the oven to burn and water from the road to evaporate on the hot day?

Who came to discover a great deal about themselves?

Miss Anderson dined out, and preferred to suppose that she had no time to think until she was on her way home along the empty road round Jakko at eleven o'clock that night. Then it pleased her to get out of her rickshaw and walk. There was an opulent moon, the vast hills curving down to the plains were all grey and silvery, and the deodars overhead fretted the road with dramatic shadows. About her hung the great stillness in a mighty loneliness in which little Simla is set, and it freed her from what had happened, so that she could look at it and cry out. She actually did speak, pausing in the little pavilion on the road where the nursemaids gather in the daytime, but very low, so that her words fell round her even in that silence, and hardly a deodar was aware. 'I will not go now,' she said. 'I will stay and realize that he is another woman's husband. That should cure me if anything will--to see him surrounded by the commonplaces of married life, that kind of married life. I will stay till she comes and a fortnight after. Besides, I want to see her--I want to see how far she comes short.' She was silent for a moment, and the moonlight played upon her smile of quiet triumph. 'He cares too,' she said; 'he cares too, but he doesn't know it, and I promise you one thing, Madeline Anderson, you won't help him to find out. And in five weeks I will go away and leave my love where I found it--on a mountaintop in the middle of Asia!'
How long does Miss Anderson plan to stay in the pavilion?
