Answer:
See explanation
Explanation:
According to the kinetic molecular theory, the molecules that compose a gas are in constant random motion.
The temperature of a gas is a measure of the average kinetic energy of the gas molecules.
When the balloon was placed in a hot water bath, the balloon becomes larger because the gas inside the balloon expands. This is because, more kinetic energy is supplied to the molecules of the gas hence they spread out.
When the balloon is placed in cold water, the kinetic energy of the gas molecules in the balloon decreases as temperature decreases hence the balloon shrinks
Ionic compounds have a strong force of attraction between the oppositely charged ions, so a lot of energy is needed in order to break the strong bonding force between those ions.
Answer:
more rapid
Explanation:
A higher temperature of fresh concrete results in a more rapid hydration of cement. This causes reduction in the setting time of the cement, also known as accelerated setting of the cement.
It also reduces the workability of the concrete; as it makes the movement of aggregates harder by reducing the lubricating effect of the cement.
