Answer:
As temperature increases the volume of given amount of gas increases while pressure and number of moles remain constant.
Explanation:
According to the charle's law,
The volume of given amount of gas is directly proportional to the temperature at constant pressure and number of moles of gas.
Mathematical expression:
V ∝ T
V = KT
V/T = K
When temperature changes from T₁ to T₂ and volume changes from V₁ to V₂.
V₁/T₁ = K V₂/T₂ = K
or
V₁/T₁ = V₂/T₂
Thus, the ratio of volume and temperature remain constant for constant amount of gas at constant pressure.
Answer : For the experiment to study the diffusion across the semi permeable membrane, following are the safety steps that will help to handle chemicals safety;
- Use droppers to transfer small amounts of chemicals into another glassware, it will prevent the unnecessary spillage of the chemical.
- Use tongs to move hot objects as they may cause severe burns.
- Check the test tubes for chips prior to using them otherwise it may leak the chemical inside it
- Washing your hands after you finishing the lab experiment, this will ensure that food is not contaminated while consuming, with the chemicals that were stuck on the hands.

Answer:
B. more it will warp space
Explanation:
Answer:
lithium is the most reactive alkali metal false as the reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal.
covalent bond is formed due to mutual sharing of electrons true
potassium is most reactive matal in activity series of metals false no lithium is more reactive than potassium
the process in which heat is given on surrounding is exothermic reaction not endothermic reaction
alkyl molecule is formed by removal of one hydrogen atom from alkane molecule true
