Boiling water. A phase change occurs when water boils.
The three common phases are <em>solid</em>, <em>liquid</em>, and <em>gas</em>. A <em>phase change</em> happens when one phase changes into different phase without a change in chemical composition.
When water boils, the liquid phase becomes a gas (water vapour or steam). The water does not change its chemical composition be each phase consists of water.
Thus, boiling water involves a phase change.
Mixing paint does <em>not</em> involve a phase change because it stays a liquid during all stages of the mixing.
A suspension consists of two phases, but the phases do not change into other phases.
Explanation:
Step one look for the longest chain of carbon atoms
Longest chain is 7 C atoms
Step 2 look for double bonds or others functional groups
it is present in 3rd carbon
Therefore IUPAC name is 3-heptene
From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.
Hope this helps...
What’s the question ??????????????????? Explain please ?
Answer:
Explanation:
The river bank can expand due to the water breaking apart and move for sediment.
Static Friction, Sliding Friction, Rolling Friction, and finally Fluid Friction.
