Answer:
The picture is most likely showing fishing/ fishery. other industries that rely on accurate weather forecast are shrimping, aquaculture, and other ocean industries
Explanation:
Answer:Statement 1 and 3 are true
Explanation:
Ca+(g) + e- ➡Ca(g)
Electron affinity of an atom or molecule is defined as the change in energy (in kJ/mole) of a neutral molecule(in gaseous state)when an electron is added to an atom to form a negative ion.Energy is released in the process thus the first electron affinities are negative.
On the other hand ionisation energy is the quantity of an energy a gaseous atom in its ground must absorb to discharge an electron.
H(g)➡H+(g) + e-
Considering both these definitions,statement 1 and 3 both falls true.
Answer:
46.85kJ
Explanation:
The specific latent heat of vaporization of water is =2.3 x 10⁶ J kg-1.
The specific heat capacity of water = 4.2×10³J/kgK
The latent heat of fusion of water= 3.36×10⁵ J/kg
The specific heat capacity of ice=2.108×10³ J/kgK
The heat of lost due to cooling of ice is calculated as follows by adding the heat lost during condensation of water vapor to the heat lost during cooling the water to freezing point plus the heat lost during freezing plus the heat lost during cooling the ice to -32.0°C
=MLv+MCΔT(water)+MLf+MCΔT(ice) where Lv=latent heat of vaporization of water , and Lf is the latent heat of fusion ice.
=(0.015kg×2.3 x 10⁶ J/kg)+(0.015kg×4.2×10³J/kgK×100K)+(0.015kg×3.36×10⁵ J/kg)+(0.015kg× 2.108×10³ J/kgK)×32K
=34500J+6300J+5040J+1011.84J
=46851.84J
=46.85kJ
