A form of matter has no fixed shape but it has a fixed volume. An example of this form of matter is :(a) krypton (b) kerosene(c) carbon steel(d) carbon dioxide
A solid substance P which is very hard is used in the construction of many buildings, especially flooring. When substance P is heated strongly, it decomposes to form another solid Q and a gas R is given out. Solid Q reacts with water with the release of a lot of heat to form a substance S. When gas R is passed into a clear solution of substance S, then a white precipitate of substance T is formed. The substance T has the same chemical composition as starting substance P.(a) What is substance P? Write its common name as well as chemical formula.(b)What is substance Q?(c)What is gas R?(d)What is substance S? What is its clear solution known as?(e)What is substance T? Name any two natural forms in which substance T occurs in nature?
State the differences between solid, liquid and gas.
The scientists now say that there are actually five states of matter A, B, C, D and E. The state A has a fixed volume but no fixed shape. The state B can be compressed very easily by applying pressure and state C has a fixed shape as well as a fixed volume. The state D is a mixture of free electrons and ions whereas state E is named after an Indian scientist and a famous physicist.(a) Name the physical states (i) A (ii) B (iii) C (iv) D, and (v) E(b) Name one substance belonging to state C which can directly change into vapours on heating. What is this process known as?(c) Name one substance which normally belongs to state B but whose solid form changes directly into gaseous state.(d) Name the most common substance belonging to state A.(e) Which state of matter makes the sun and other stars to glow?
Pressure and temperature determine the state of a substance. Explain this in detail.
Does every mineral have a definite and a fixed composition? Explain.
Name the temperature at which :(a) a liquid changes into a gas.(b) a solid changes into a liquid.
