The volume of the sample is 48.39 cm³.
<h3 /><h3>What is volume?</h3>
The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface
To calculate the volume of the sample, we use the formula below
Formula:
- D = m/v
- v = m/D................ Equation 1
Where:
- m = Mass of the smaple
- D = Density of the sample
- v = Volume of the sample.
From the question,
Given:
Substitute these values into equation 1
Hence, the volume of the sample is 48.39 cm³.

climate change is a change in climate in the Earth 's normal weather patterns for different climates. it normally changes little by little over the years.the earth is cooler and warming .now it's getting warmer. this phenomenon is also known by as globall warming.it's causes are:
1.energy uses
2.agriculture and land use 3.Transport 4.Industries 5.Growing demands for food and water
A greenhouses is made from glass or clear plastic. It is useful for growing plants in winter in cooler climates.
sorry i don't know last one .
The 2015 United Nations Climate Change Conference, COP 21 or CMP 11 was held in Paris, France, from 30 November to 12 December 2015.

Explanation:
119.7kPa
Explanation:
Given parameters:
Pressure of gas in balloon = 111kPa
Temperature of gas = 22°C
Final temperature = 45°C
Unknown:
Final pressure = ?
Solution:
Since the gases in the balloon have the same number of moles. We can apply a derivative of the combined gas law to solve this problem.
At constant volume the pressure of a given mass of gas varies directly with the absolute temperature.
P1 is the initial pressure
P2 is the final pressure
T1 is the initial temperature
T2 is the final temperature
convert from celcius to kelvin:
tK = 273 + tC
T1 = 273 + 22 = 295K
T2 = 273 + 45 = 318K
P2 = 119.7kPa

Answer:
the total mass after chemical burn is 700 gram
Explanation:
Given data
glass mas s= 200 gram
chemical mass = 500 gram
total mass = 700 gram
to find out
what is the total mass after chemical burn
solution
we have given 200 gram + 500 gram = 700 gram
and we know here according to question that
container is sealed so total mass remain in container before burning and after burning
no air will release in seal container so
mass will be same as 700 gram
hence the total mass after chemical burn is 700 gram
The series circuit has the higher equivalent resistance, but to find the larger equivalent resistance you have to use Ohm's law (V2=I2R2), the power dissipated by the resistor can also be found using P2=I22R2=V22R2. To find the equivalent resistance of the circuit, notice that the parallel connection of R2 and R3 is in series with R1, so the equivalent resistance is Req=R1+(1R2+1R3)−1=1.00Ω+(16.00Ω+113.00Ω)−1=5.10Ω.
Hope this helps!
