Conduction
In metals, the electrons of each atom are delocalized, which means they are free to move about in the structure of the metal. When heat is applied at one end of the metal, the electrons there are excited and collide with surrounding particles, transferring their energy to them. This is what makes metals very good conductors of both heat and electricity.
Answer:
The light bends
Explanation:
When it passes through two different densities it changes directions, causing a bend
First solve the mass of 37.9 L seawater
M = 37.9 L ( 1000 ml / 1L ) ( 1.03 g / ml)
M = 39037 g
Then convert it to lb
M = 39037 g ( 1 lb / 453.592 g)
M = 86.06 lb
<span>Total weight = 86.06 lb + 59.5 lb = 145.56 lb so it can

Answer:
The ΔG° is 29 kJ and the reaction is favored towards reactant.
Explanation:
Based on the given information, the ΔH°rxn or enthalpy change is 41.2 kJ, the ΔS°rxn or change in entropy is 42.1 J/K or 42.1 * 10⁻³ kJ/K. The temperature given is 289 K. Now the Gibbs Free energy change can be calculated by using the formula,
ΔG° = ΔH°rxn - TΔS°rxn
= 41.2 kJ - 289 K × 42.1 × 10⁻³ kJ/K
= 41.2 kJ - 12.2 kJ
= 29 kJ
As ΔG° of the reaction is positive, therefore, the reaction is favored towards reactant.
0.88qt
Explanation:
Given parameters:
Density of ebony wood = 1.174g/ml
Mass of wood = 2.1549lb
Unknown:
Volume of the wood in quarts = ?
Solution:
Density is defined as the mass per unit volume of a substance.
Mass is the quantity of matter the wood contains.
Volume is the space it occupies.
To solve this problem, convert the mass form pounds into grams and plug into the density equation to find volume.
Then convert the volume from mL to quarts.
Density = 
Volume = 
1 pound = 453.592g
2.1549 lb = 2.1549 x 453.592 = 977.5g
Volume = 
= 832.6mL
1 quart = 946.353mL
Therefore 832.6mL x 
= 0.88qt
