The carbon dioxide in the headspace above the liquid is at higher pressure than atmospheric pressure outside the can.
The gas is at a lower volume initially but suddenly has a larger volume available when the can is opened.
The change in pressure as the gas rapidly moves to become dispersed through its new volume causes the "whoosh" sound.
The gas law that applies is Boyle's law.
This above is the exact answer for edgunity
Answer:
3.58J/g°C is the specific heat of the metal
Explanation:
The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:
Q = S*ΔT*m
<em>Where Q is energy = 1362J</em>
<em>S is specific heat of the material</em>
<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>
<em>And m is the mass of the material = 15.2g</em>
Replacing:
S = Q / ΔT*m
S = 1362J / 25°C*15.2g
<h3>3.58J/g°C is the specific heat of the metal</h3>

Answer:</h3>
The rate of sea level change is the fastest
<h3>
Explanation:</h3>
To determine the process which is the fastest we need to determine the rate at which each occurs in meters per year.
Rate of sea level changes is 10 m per 1,000 years
Therefore, the rate of sea level change = 10 m ÷ 1000 years
= 0.01 m/yr
Regional erosion occurs at 2 m per 1,000 years
Therefore, Rate in meters per seconds = 2 m ÷ 1,000 years
= 0.002 m/year
Uplift occurs at a rate of 0.1 m per 1,000 years
Thus, rate in meters per seconds = 0.1 m ÷ 1,000 years
= 0.0001 m/yr
Therefore, the rate of sea level change is the fastest at a rate of 0.01 meter/year
Answer:
Only 4 %
Explanation:
Just about 4 percent of the known universe overall mass consists of atomic nuclei and is therefore described by chemical components. This proportion is around 15 percent of the total mass, with dark energy becoming the majority of the material .
