Answer:
<h2>Density = 0.75 g/cm³</h2>Explanation:
Density of a substance is given by
<h3>From the question
mass of the wood = 180 g
Since the wood is a cuboid we can find the volume using the formula
Volume = length × width × height
From the question
length = 10cm
width = 6 cm
height = 4 cm
Volume = 10 × 6 × 4 = 240 cm³
Substitute the values into the above formula and solve for the Density
That's
<h3>We have the final answer as
<h3>Density = 0.75 g/cm³</h3>Hope this helps you
Answer: The pressure will be 411 GH.
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the pressure will be 411 GH.
