A student would like to determine how heating a liquid changes its volume. The student hypothesizes that the liquid will increas

frez [133]

Answer:

B. The volume of the liquid should be measured before it is heated.

Explanation:

A student made serious mistake that he did not measure the volume of the liquid before heating.

The scientific experimentation along with care and attention need a proper protocol which a scientist needs to follow to get the results.

The initial hypothesis of the student shows that he wants to know the change in volume, so it is inevitable to calculate the initial volume to know the difference after the completion of experiment.

All other options seem less appropriate than Option B, therefore B is the right answer.

I hope it help!

Economic benefits of forest

omeli [17]

Forests play an important role in the economic development of a country. They provide several goods which serve as raw materials for many industries. Wood grown in forests serves as a source of energy for rural households.

Most of the world’s paper is made from wood and one rather reliable index to the degree of economic development of a country is its per capita consumption of paper. As an economy develops economically, paper is used as packaging material, in communications and in scores of other uses. No really satisfactory substitute for paper exists for many of its uses.

While it has long been recognized that forests play many roles in the economic development of a country in addition to providing wood fiber for many uses, the non-wood outputs of forests are coming increasingly to be recognized and valued everywhere in the world. Forests have watershed values especially in areas with fragile and easily eroded soils; tree cover may be highly valuable simply as protection to the watershed.

Forests are valued as a place for outdoor recreation. The kinds of forests most valuable for outdoor recreation are not always the same as the kinds most valuable for wood production and vice versa. The dense forest with trees closely spaced to take full advantage of the sunlight, moisture and fertility to grow wood, is often less attractive to the recreationist than a more open forest.

Forests are the home for many species of wildlife including mammals, reptiles and birds. Some of these forms of wildlife are clearly valuable to man. Ecologists have been much disturbed at the reduction in wildlife numbers, sometimes to the point of extinction, as tropical forests are cleared.
