Assuming the edge length of the cube is m.
Since the cube's sides are all equal, you can find its volume using the formula:
volume of cube = m^3
Now, using the provided edge length:
volume = (4.33)^3 = 81.1827 cm^3
According to unit conversion standards, 1 cm^3 = 0.001 liters.
So:
volume of cube = 81.1827 cm^3 = 0.0811827 liters
After four hours of cooling, the soup reached a temperature of 140 F (or) 42 C.
Explanation:
A food worker allowed a cup of soup to cool for two hours,
step 1: The temperature attained in two hours is 70 F (or) 21 C
step 2: Consequently, in four hours, this doubles the value
Therefore, the temperature after four hours is 2(70)= 140 F (or) 2(21)= 42 C
Answer:
Joe correctly mixed the solution.
Explanation:
When evaluating both procedures, it's evident that both Jennifer and Joe weighed the same amount of potassium phosphate, which isn’t the variable here.
The difference is that Jennifer added the solid to 1.0 liters of water, resulting in a final volume greater than 1.0 L, thus her concentration will be lower than 1.0 M.
Joe's solution has a final volume of 1.0 L, which is why his preparation is accurate.
Prior to beginning the calculations, let’s convert the units into those we require:
1- For the distance:1 mile = 1609 meters
= 1609 x 100 = 160900 cm
= 1609 / 1000 = 1.609 km
= (160900 x 1 ) / 2.54 = 63346.45 in
2- For the time:13 minutes = 13 / 60 = 0.2166 hours
= 13 x 60 = 780 seconds
Now, we can proceed with the calculations:
velocity is determined using this formula:
velocity = distance / time
(a) in/seconds
velocity = 63346.45 in / 780 sec = 81.213 in / sec
(b) m/min
velocity = 1609 m / 13 min = 123.769 m/min
(c) km/hr
velocity = 1.609 km / 0.2166 hr = 7.428 km/hr
The correct selection is B) Initially, the substance existed as a gas, and subsequently, it transformed into a liquid. Gas particles move apart and freely, while in contrast, liquid particles are in close proximity and move past one another. I hope this clarifies the matter!
