Setting concrete at 50°C is preferable to setting it at 5°C. Why? At 50°C, the concrete sets to have a lesser final compressive strength.
At 50°C, the concrete sets to have a greater final compressive strength.
At 50°C, the concrete sets more quickly.
At 50°C, the concrete sets more slowly.

No. an alpha particle is a pair of protons and a pair of neutrons, i.e. a helium

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
