Answer:
about the same
Explanation:
Thermal energy is constant at a certain temperature in general. The energy is denoted by
Where,
is the Boltzmann constant
T is the absolute temperature
Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.
Thus,
The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.
Answer:
70g
Explanation:
Rate = 35g of NaCl can dissolve in 100g of H2O
Use proportions for 200g of H2O:
Since 200 is double of 100, x needs to be double of 35.
Therefore the maximum amount of NaCl that can dissolve in 200g of water is 70g.
