Answer:
14700J
Explanation:
From the question given, the following were obtained:
M = 100g
ΔT = 35° C
C = 4.2J/g °C
Q=?
The heat transferred can calculated for by using the following equation
Q = MCΔT
Q = 100 x 4.2 x 35
Q= 14700J
Answer:
answer is b
use pv=nRT
p directly proportional to moles(n)
p1/p2=n1/n2
p/p2=n/2n
p2=2p
Answer: 0.0624 atm
Explanation:-
According to the ideal gas equation:

P = Pressure of the gas = ?
V= Volume of the gas = 45.0 L
T= Temperature of the gas = -10.0°C = 263 K 
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas
Moles of gas=

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm
The environment modifies.
Explanation:
A modification of the environment can lead to population changes overtime. The environment is very important for population dynamics.
It is predominantly made up of the factors that affects organisms and where they live.
If the resources in an environment gets depleted, organisms will be force to migrate from that place to another in search of more nutrient areas.
This and many other factor like climate, stability, etc causes changes to the population through time.
