Answer:
q(ice) = -q(warm water)
Explanation:
Ice removes energy if ice is put in warm water and ice retains the very same amount of energy. Thus the water temperature heat sign is negative, and the ice heat sign is positive.
Answer:
<u>At 268.82°C</u> volume occupied by nitrogen is 10 liters at pressure of 900 torr.
Explanation:
Given:
Volume of a sample of nitrogen = 5.50 liters
Pressure = 900 torr
Temperature = 25°C
To find the temperature at which the nitrogen will occupy 10 liters volume at same pressure.
Solution:
Since the pressure is kept constant, so we can apply the temperature-volume law also called the Charles Law.
Charles Law states that the volume of a gas held at constant pressure is directly proportional to the temperature of the gas in Kelvin.
Thus, we have :
∝ 

where
is a constant.
For two samples of gases, the law can be given as:

From the data given:



We need to find
.
Plugging in values in the formula.

Multiplying both sides by
.


Multiplying both sides by 



Thus, at 268.82°C volume occupied by nitrogen is 10 liters at pressure of 900 torr.
The formula for solving the inertia (I) is I=mr² where "m" represents the mass of an object and "r" represents the perpendicular distance to the rotation axis.
item 1= 100 kg rock
Item 2= 5kg book
item 3= 60kg person
item 4=2000kg car.
The answer is the last item which is a 2000kg car.
Answer:
Answer: C
Explanation:
The closer the city is by the ocean, the cooler it will get because of the winds it is created from the ocean. Meanwhile, Atlanta is slightly away from the ocean but wont be as cool as the Tybee Island. So the heat will hit more to the city away from the ocean.
