Explanation:
workdone = force x distance
force = mass x acceleration
30 x 10 = 300N
300N x 1m
workdone= 300J
I am pretty sure the correct answer is C. Water has large heat capacity meaning it can absorb a lot of energy before changing temperature. That helps the body regulate heat since it can be exposed to different environments and experience small temperature changes.
I hope this helps. Let me know if anything is unclear.
Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. ... In the central nervous system, axons are myelinated by oligodendrocytes, thus lack neurilemma.
The boiling of water and sublimation of iodine crystals are endothermic processes.
Answer: Option B & C
Explanation:
Endothermic process are the classifications of chemical reactions where the heat is absorbed by the system from the surroundings. As the matters can exists in three phases like solid, liquid and gases.
The endothermic process occurs by absorption of heat energy by the system. So according to the given options, the boiling of water and iodine crystal sublimation follows endothermic process. In the boiling of water occurs when the water molecules absorb heat from the surrounding and convert to gas phase.
Similarly, the sublimation of iodine crystals also require heat energy from the surrounding to break the bonds of the iodine crystals to sublimate to gas phase. Thus the boiling of water and sublimation of iodine crystals are the examples of endothermic processes.
