Answer:
4/15
Explanation:
15/15 - 11/15 = 4/15
If 11/15 is the probability that it'll rain tomorrow, then the rest should be the probability that it'll not rain tomorrow.
Answer:
When the water is mixed with water at lower temperature the effective temperature of the system (i.e the water at lower temperature) will increase, thereby increasing it's entropy
Explanation:
The answer that "the entropy will is increases" is correct as:
The water at 90° C i.e at higher temperature is mixed with the water at 10° C i.e the water at the lower temperature.
The water at lower temperature will have molecules with lower energy while the water with higher temperature will have molecules undergoing high thermal collisions. Thereby, when the water is mixed with water at lower temperature the effective temperature of the system (i.e the water at lower temperature) will increase, thereby increasing it's entropy.
Therefore, the answer is correct with respect to the water at lower temperature.
Meanwhile, for the water at higher temperature , the temperature of the system will decrease. Thus, the entropy of the water at higher level will decrease.
Answer:
0.04167mole
Explanation:
To convert gram to mole,
C6H12O6
C - 12
H - 1
O - 6
There are 6 moles of C, 12 mole of H and 6 mole of O
Therefore, multiply each number of mole by the mass of each element
C - 12 * 6 = 72
H - 1 * 12 = 12
O - 16 * 6 = 96
The molar mass of C6H12O6 = 72 + 12 + 96
= 180g/mol
Dividing the number of mass by the mm
= 7.50g / 180g/mol
= 0.04167 mole
Answer: heat required to raise the temperature
Explanation: Heat equation is represented as:

Q= heat required to raise the temperature
m= mass of the substance
c = heat capacity of substance
