Answer:
Specific gravity of mineral = 2.6
Explanation:
Given data:
Density of mineral = 2.6 g/cm³
Specific gravity = ?
Solution:
Specific gravity:
Specific gravity of a substance is ration of density of substance and the density of reference substance. It is unit less quantity.
Mostly water is taken as reference substance.
The density of water is 1 g/cm³
Thus the specific gravity of mineral is,
Specific gravity of mineral = density of mineral /density of water
Specific gravity of mineral = 2.6 g/cm³ / 1 g/cm³
Specific gravity of mineral = 2.6
Answer:
endothermic means energy is taken in and temperature increases.
Answer:
it is the second one. Lead
Answer:
FALSE
Explanation:
Assuming that the gas is ideal
Therefore the gas obeys the ideal gas equation
<h3>Ideal gas equation is </h3><h3>P × V = n × R × T</h3>
where
P is the pressure exerted by the gas
V is the volume occupied by the gas
n is the number of moles of the gas
R is the ideal gas constant
T is the temperature of the gas
Here volume of the gas will be the volume of the container
Given the volume of the container and number of moles of the gas are constant
As R will also be constant, the pressure of the gas will be directly proportional to the temperature of the gas
P ∝ T
∴ Pressure will be directly proportional to the temperature
