Answer: The answer is C. A mercury thermometer is better to measure very small changes in temperature.
Explanation:
i took this quiz and this is the answer .
A) A mercury thermometer can measure the freezing point of a liquid that freezes at −80 °C.
B) An alcohol thermometer can measure the boiling point of a liquid that boils at 80 °C.
C) A mercury thermometer is better to measure very small changes in temperature.
D) An alcohol thermometer is better to measure the boiling points of colorless liquids.
2. High tempertaure and low pressure
3. HCL,NH3,H20
4. higher collisions ieThe greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
Explanation:
Expansion:
1. Suppose gas particles are moving in a linear fashion but if they collide with some thing they will fil that. This explains expansion theory of gases.
Fluidity: The gas molecules are in dependent of each other and have low density, they are in constant motion hence have fluidity.
low density: The gas molecules are far apart as compared to solid and liquid hence have low density.
compressibility: Due to the large distance between the gas molecules they collide with each other and vessel wall and when the space is constricted they start moving faster. They are elastic in nature.
Diffusion: Yes, because when gas is mixed it starts moving in the mixture randomly.
2. The molecules in real gas are at large distance. The high temperature and low pressure real gas would behave ideally. Because increase temperature would cause higher movement of gas particles.
3. HCL, NH3 and H2O are polar gases they will have relatively different attractive forces between them.
4. The greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
5. The gas particles get closer, enough pressure not provided. It increases the kinetic energy as heat is produced due to compaction of molecules. The particles would not move and will become liquid causing volume to increase.
6. The gas molecules start moving rapidly, move farther apart .Volume and pressure also increases.
Answer:
The halogens are extremely reactive, whilst the noble gases are mainly inert.
Only some noble gases tend to form compounds, such as xenon and krypton. However, some like helium, almost have no compounds at all.
Noble gases also have octet rule shells, which causes the little reactivity associated with them.
To form bonds with noble gases, a lot of energy is required to form those bonds.
Halogens, on the other hand, are extremely reactive. Compounds like chlorine and fluorine must be stored carefully, as they will oxidise anything that they can find, just to get one extra electron to get an octet configuration.
Hope this helps :)
No; it can only ever be at half pressure
hope this helps (;
