Answer: (Assuming we’re going by degrees Fahrenheit) I’d say 140.
Explanation: -40 would be beyond freezing point for water which is 32 degrees Fahrenheit and 40 would nearly be freezing point. For water to transform into its gas phase, the temperature would need to be greater. Therefore, 140 degrees Fahrenheit makes the most sense.
Although I did search it up and 212 degrees Fahrenheit (100 degrees Celsius) is the proven temperature at which water transforms into water vapor so... not sure if there’s more to the question or I’m interpreting the question wrong.
Heat is given by multiplying the specific heat capacity of a substance by mass and the change in temperature. The heat capacity of water is Approximately 4184 J/K/C.
Therefore, heat = mc0 mass in kg
= (422/1000) × 4184 × (100-23.5)
= 135072.072 J
Latent heat of vaporization is 2260 kJ/kg
Thus the heat will be 0.422 × 2260000 = 953720 J
Heat to raise steam from 100 to 150
2000 × 0.422 ×50 = 42200 J
Thus the heat required is (135072.072 + 953720 + 42200) = 1330992.07 Joules or 1330 kilo joules
Answer:
They have to
Explanation:
It occurs when 2 or more molecules interact and their bonds change
Answer:
This answer I think it is Al,F
The atom that is most likely to lose an electron is lithium (Li).
<h3>What is electronegativity?</h3>
Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons when forming bonds.
On the other hand, electropositivity is the tendency of an atom to release electrons to form a chemical bond.
Chemical elements that lose electrons become positively charged while elements that gain electrons become negatively charged.
Metals are most likely to lose electrons to form positive ions. Examples of metals are lithium in group 1, calcium in group 2, aluminium in group 3 etc.
