Answer:
They are made in the Heavens, in Stars.
Explanation:
The relationship between boiling point of liquid and elevation is inverse. Means, with increase in altitude the boiling point will decrease. This is because with increase in altitude the atmospheric pressure will decrease, as boiling point is temperature at which vapor pressure of liquid becomes equal to the atmospheric pressure.
Hence, the city where boiling point of specific liquid is 141 °C is at higher elevation. And the liquid with boiling point of 145 °C is experiencing higher atmospheric pressure due to less altitude of the city it is present in.
Answer:
The correct answer is option D, Sb
Explanation:
Atomic radius of As = 185 pm
Atomic radius of N = 155 pm
Atomic radius of P = 195 pm
Atomic radius of Sb = 206 pm
If we arrange the following element on the basis of their atomic radius in the increasing order , we will get the following
N (155 pm) < As (185 pm) < P (195 pm) < Sb (206 pm)
Thus among all the given element Sb has the largest atomic radius
Answer: The temperature is there to confuse you on purpose. Density changes with temp, but in these type of problems, they mean nothing
Explanation:
The formula for density is mass per unit of volume.
We dont have to do any conversions here so it boils down to division and multiplication.
Now for the second part:
