The addition of 15 g of salt to a sample of pure water causes its freezing point to be reduced by 1.3°C. What would be the effect of dissolving an additional 15 g of salt into the solution? A. There would be no additional effect on the freezing point. B. The freezing point would be depressed (decreased) by an additional 1.3°C. C. The freezing point would be depressed by 15°C. D. The freezing point would become higher.

option A

There will be no effect in the freezing point of water.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
