Answer :
The substance is in the gas phase only in region → 5
The substance is in both the liquid and the solid phase in region → 2
The substance is in only the liquid phase in region → 3
The melting point is the temperature at region → 2
The boiling point is the temperature at region → 4
Explanation :
Six phases of substance:
- Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.
- Freezing : In this process the phase changes from liquid state to solid state at constant temperature.
- Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.
- Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.
- Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.
- Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.
Answer:
The device can collect up to 1.5 kg (3.3 lbs) of waste per day and holds a total of 20 kg (44 lbs) of waste. To illustrate this more vividly: A Seabin can collect up to 90’000 plastic bags, 37’500 coffee cups or 16’500 PET bottles per year.
Explanation:
Not sure what you mean??
Answer:
Sedimentary Rock. You know from the fossils and remains of shells inside.
Explanation:
If it were igneous, the fossils would be melted away. Maybe not with metamorphic, but it's most likely sedimentary.
The hybrid atomic orbitals are formed by the combination of the valence orbitals on an atom. The hybrid orbitals formed have different energy and shape compared to the atomic orbitals that combine to form the hybrid orbitals. Hybrid orbitals help in explaining the shapes of the molecules and other bonding properties.
Therefore the correct answer will be,
b. A mixture of the valence orbitals in an atom
e. There are as many hybrid orbitals as there are valence orbitals that mix together.
f. Hybrid orbitals have a different shape and different energy than the atomic orbitals of which they are made
Wavelength decreases as frequency increases.
Imagine a heart rate graph. As the heart beats faster, frequency increases and the time between heartbeats decreases (wavelength).
