Explanation:
hydropower energy is:
-renewable
-clean (doesn't produce toxins or emit harmful gases into the atmosphere)
-environment friendly
-cheap once installed
The sun's energy would be circulated through convection. This is because whenever you see the word "circulate", there is a pretty good chance it has something to do with convection.
D- seismic waves
Geologists use an indirect method to study Earth's interior. Earthquakes produce seismic waves. Geologists record the seismic waves and study how they travel through Earth.
Answer:
(A) The intermolecular attraction between HF molecules are stronger than between HCl molecules mainly to due hydrogen bonding.
Explanation:
Since Flourine is highly electronegative and as such, when it bonds with Hydrogen it forms a hydrogen bond. Whereas the HCL molecule is a polar molecule whose inter-molecular forces are dipole dipole interactions. Although a Hydrogen bond is a type of dipole dipole interaction it is stronger than the traditional dipole dipole forces and London dispersion forces. HF also has a shorter bond length which makes the bond and inter-molecular forces stronger as compared to HCL.
