Answer:
852000 J
Explanation:
The following data were obtained from the question:
Mass (M) = 600 g
Change in temperature (ΔT) = 2 °C
Specific heat capacity (C) = 710 J/g℃
Heat transfered (Q) =?
Thus, we can obtain the the heat transfered to the diamond by using the following formula:
Q = MCΔT
Q = 600 × 710 × 2
Q = 852000 J
Therefore, the energy transfered to the diamond by heat is 852000 J
The answer is the gaz inside the bag would expand. (A)
4.67 is the right answer
+ − − log(7,5 ∗ 10−3) − log(6.2 ∗ 10−8) ,34 ,24
= 2 = 2 =4.67
Answer:
d. directly proportional to the number of moles of the gas.
Explanation:
The formula for the partial pressure of a gas is written as -
P = n * P ( total )
P = partial pressure of the gas ,
n = mole fraction of the gas ,
P ( total ) = Total pressure of the mixture of gas .
Hence , from the above equation ,
the partial pressure is directly proportional to the mole fraction , i.e. , on increasing the number of moles of gas , the partial pressure increases .
