Answer:
C
Explanation:
Let's consider the conservation of energy
Energy can not be destroyed or created energy can be transferred one form energy to a another form of energy.
(A) Then all form of energy can be transfer into any form of energy . There for all forms of energy can be transformed to thermal energy
(B) This is the law of conservation of energy
(C)Potential chemical energy can be transferred into any form of energy. It's not only to kinetic energy
(D) Some amount of thermal energy always released when it's transferred energy due to reaction forces or frictional forces.
Answer: Yes
Explanation: A molecule has a bond dipole but not have a molecular dipole.
Dipole moment: dipole moment is the product of the distribution of the charge of the molecules and the distance between of the molecules.
Example:
lets take an example of
molecule in which two electro negative oxygen atoms are attached with Carbon atom. Oxygen being electro negative will attract the shared pair electrons towards itself and partial negative charge will create on oxygen atom and partial positive charge on carbon atom C.
due to formation of partial positive and partial negative charges dipole moment is created between oxygen and Carbon bond on both the sides in opposite direction.
Since, the dipole moment acting in opposite direction the net dipole moment in the molecule is zero.
Hence, Yes, a molecule has bond dipoles but not have a molecular dipole.
A and C because stronger attractions means it needs more energy to break them so a higher temperature is needed
Answer: I think the answer is heat flows from the lemonade to the ice
Explanation: the heat transports to the lemonade which makes the lemonade hot and the ice will melt if the drink is hot
Explanation:
Diffraction is a characteristic phenomenon for waves, and is based on their variance to find an obstacle or a crack. The diffraction and interference are inseparable phenomena, which are so harder to identify. Since diffraction is a specific type of interference.
if the point are in the order 2, and
the equation is d×senx=mL y at m=2
