Hey there!
Volcanoes can cause several different changes to surfaces of the Earth. Of course one way is when lava flows and ejection of cinder, pumice, and ash build up to create cones of volcanoes and volcanic mountains. In addition, volcanic activity, such as basalt floods, lay thick, dense layers of rock on a landscape.
Hope I made your day a bit easier!
Have a good day and Happy Halloween!
Answer:
0.17094 liters
Explanation:
-For STP, Pressure=1 atm and Temperature=273K
-We apply the combined gas law which relates temperature, pressure and Volume:
-We therefore equate the relationship at different temperatures as follows:
Hence, the new volume is 0.17094 liters
Answer:
V = 5 cm³
ρ = 4 g/cm³
Explanation:
Step 1: Calculate the volume (V)
We have a wooden cuboid of dimensions 5 cm × 1 cm × 1 cm. We can calculate its volume using the following expression.
V = 5 cm × 1 cm × 1 cm
V = 5 cm³
Step 2: Calculate the density (ρ)
The density is equal to the mass divided by the volume.
ρ = m / V
ρ = 20 g / 5 cm³
ρ = 4 g/cm³
60+68=128
128/2=64
so the answer is 64
I hope this helped
