I am Glad you ask!!
The metals are conductors and insulators are plastics which energy cant flow threw.
So in a torch any metal helps the energy circulate and keep its flow.
Hope this helps :)
Answer:
3.1 M
Explanation:
3.1 M has the highest concentration of sweet tea so it should taste the sweetest.
Answer:
1.73 atm
Explanation:
Given data:
Initial volume of helium = 5.00 L
Final volume of helium = 12.0 L
Final pressure = 0.720 atm
Initial pressure = ?
Solution:
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
P₁ × 5.00 L = 0.720 atm × 12.0 L
P₁ = 8.64 atm. L/5 L
P₁ = 1.73 atm
Answer:
The substance occupy 961.54 cm³ space.
Explanation:
Given data:
Mass of substance = 750.00 g
Density of substance = 0.78 g/mL
How much space it occupy = ?
Solution:
The space occupy by the substance is equal to its volume. Thus we will calculate the volume by applying density formula. Which is actually the space cover by substance.
d = m/v
d = density
m = mass
v = volume
0.78 g/mL = 750.00 g/ v
v = 750.00 g/ 0.78 g/mL
v = 961.54 mL
1 mL = 1 cm³
v = 961.54 cm³
Thus substance occupy 961.54 cm³ space.
