Answer:
The atoms in the cup of coffee have more energy.
Explanation:
The difference between the hot cup of coffee and the piece of ice is their temperature. The hot cup of coffee has a higher temperature than the ice.
The relationship between the energy and temperature is a direct relationship. This means that higher temperature means higher kinetic energy and vice versa.
Since the hot cup of coffee has a higher temperature, it means it also have the highest amount of energy. The correct option is;
The atoms in the cup of coffee have more energy.
Answer:
D
Explanation:
objects with larger mass have more gravitational pull
Moles of P = 56,4g/30,974g/mole = 1,82 moles P
moles of O = 43,6/15,999 = 2,73 moles of O
converting to the simplest ratio:
For P : 1,82/1,82 = 1
For O : 2,73/1,82 = 1,5
1 P and 2 oxygens.
PO2 -> the empirical formula
hope this help
