What are the three states of matter? Erupting volcanoes release rivers of hot molten rock that cool and solidify as they move away from the volcano cone. Compare th... show full transcript
Step 1
Answer
The three states of matter are:
Step 2
Answer
In molten lava, the particles have increased freedom to move as they can slide around one another, resulting in a less rigid structure. Conversely, in solidified rock, the particles are unable to move freely and are fixed in place, leading to a rigid structure.
Step 3
Step 4
Answer
To calculate the volume occupied by the gas at a temperature of 750 °C, we will use the combined gas law:
Given:
Assuming pressure is constant (), we can simplify to:
Calculating:
Therefore, the volume occupied by the gas is 5.2 litres.
