Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water.

What are the physical properties of matter, and how many primary states are there for matter?

Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

What is it called when rock and soil settle to the bottom of calm water?

Independence with Partition: The British began to see India's independence as inevitable; however, only a few seemed to understand the vital role of the religious groups. Britain prepared a parliamentary democracy with majority rule, but the majority were Hindusand Hindus, Muslims, and Sikhs had been killing each other in war for many centuries. Nehru's Congress Party, largely Hindu with a socialist leadership, wanted a parliamentary democracy. As counterweight, British legislation reserved parliamentary seats for religious minorities, but the Punjab and Bengal had such a complicated mixture of Hindus, Muslims, and Sikhs that it was not possible to avoid fights over how separate constituencies were to be formed. The seeds of future trouble were sown. The legislation on reserving seats gave the Muslims the basis for an alternative to an India in which they were only a quarter of the population: Partition. In 1930, the poet Muhammad Iqbal proposed a separate Muslim homeland in the northwest of India. A small group of Indian Muslims at Cambridge came up with the name Pakistan, using the initials of the Punjab, Afghania (N.W. Frontier Province), Kashmir, and Sind (at the same time producing the word pak, meaning "pure"), and adding "stan," the Persian suffix for the word "country. " The Muslim campaign for Partition was led by London-trained Bombay lawyer, Muhammad Ali Jinnah. Meanwhile, Gandhi vehemently opposed any dismemberment of the country, and tried to keep people united by fasting to uphold the spirit of love, and by focussing on the common adversary: the British. Advocating civil disobedience, he led his famous Salt March to the sea, to scoop up salt and circumvent the hated British salt tax. This put more than 60,000 in jail. Against this militancy, World War II did not elicit the solidarity of the first. Indians courageously fought alongside the British troops, in Burma, the Middle East, and Europe, but Gandhi saw the British as a provocation for Japanese invasion and was jailed yet again, for launching a "Quit India" campaign in the year 1942. Some anti-British extremists saw the Japanese as an Asian liberator. Winston Churchill didn't want any Indian independence and so it was probably as well for India that he was defeated by Attlee's Labor Party in 1945. With riots growing ever more bloody in Bengal, Bihar, and the Punjab, India's last viceroy, Lord Mountbatten, kept a mandate to make the British departure as quick and as smooth as possible. Quick it wassix months after his arrivalbut not smooth.
Why would Nehru's largely Hindu Congress Party want a parliamentary democracy?
