At 1.70 atm, a gas sample occupies 4.25 liters. If the pressure in the gas increases to 2.40 atm, what will the new volume be?
Answer:
3.01L
Explanation:
Given parameters:
Initial pressure, P1 = 1.7atm
Initial volume, V1 = 4.25L
Final pressure, P2 = 2.4atm
Unknown:
Final or new volume, V2 = ?
Solution:
To solve this problem, we use Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
P1 V1 = P2 V2
P1 is the initial pressure
V1 is the initial volume
P2 final pressure
V2 final volume
1.7 x 4.25 = 2.4 x V2
V2 = 3.01L
Answer:
Relative Dating
Explanation:
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
The answer to this is C jellyfish i am positive

Answer:
No the resistance of a given circuit does not remain constant if the temperature of the circuit changes.
Explanation:
The resistance of any resistor used in a circuit depends upon the temperature of that resistor. This can be mathematically represented as follows
Where,
R(t) is resistance of any resistor at temperature t
is the resistance of the resistor at time of fabrication
α is temperature coefficient of resistivity it's value is different for different materials
This change in the resistance is the cumulative effect of:
1) Variation of resistivity with temperature
2) Change in dimensions of the resistor with change in temperature
