The change in temperature is greater when the water is heated with the use of the fire caught by the food substance, then the energy content in the food substance is higher because the heat energy is greater, since the heat energy is absorbed by the water when the fire is kept under the test tube containing water. The formula indicates that if the change in temperature is greater when the mass of the substances and the volume of water are constant, then the heat energy is higher.
Answer:
The Duck will sit silently on the Kangaroo, cover her wet webbed feet with woolen socks, and be on her best behavior, doing nothing but "Quack".
Explanation:
In the story of the Duck and the Kangaroo, a bored Duck wanted to explore the world outside of the pond where she lives. So, she made a request to a Kangaroo to carry her on his back while he hops to different parts.
Although agreeing to the Duck's plan, the Kangaroo had one objection- the Duck's wet, cold feet might affect his joints. So, the duck got woolen socks to cover her wet webbed feet, smoke cigars to keep herself warm, and also use a cloak. Moreover, she also promised to sit quietly on his back and do nothing but "Quack" so that the Kangaroo will feel comfortable.
