Initial volume of the balloon = 
= 348 mL
Initial temperature of the balloon 
= 
Final volume of the balloon 
= 322 mL
Final temperature of the balloon = 
According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.
On plugging in the values,
Therefore, the temperature of the freezer is 276 K
The heat released by the water when it cools down by a temperature difference AT
is Q = mC,AT
where
m=432 g is the mass of the water
C, = 4.18J/gºC
is the specific heat capacity of water
AT = 71°C -18°C = 530
is the decrease of temperature of the water
Plugging the numbers into the equation, we find
Q = (4329)(4.18J/9°C)(53°C) = 9.57. 104J
and this is the amount of heat released by the water.
Answer:
The correct answer is D. How gravity interacts with planets
Explanation:
Einstein's theory of relativity formulated in 1915 introduces the following concepts:
- Formula E = mc2 (relationship between energy, mass, speed of light)
- How nuclear energy is produced
-After seeing a solar eclipse, gravity is interpreted geometrically (which is an effect of distortion)
-Relative time
Answer:
C) 4.24 x 
Explanation:
E = Δm
Δm = 0.0284 x 1.66 x 
kg = 4.714x
kg
putting value in above equation
E = 4.714xkg x (3x
= 4.24 x
Answer:
Gases are easily compressed. We can see evidence of this in Table 1 in Thermal Expansion of Solids and Liquids, where you will note that gases have the largest coefficients of volume expansion. The large coefficients mean that gases expand and contract very rapidly with temperature changes. In addition, you will note that most gases expand at the same rate, or have the same β. This raises the question as to why gases should all act in nearly the same way, when liquids and solids have widely varying expansion rates.
The answer lies in the large separation of atoms and molecules in gases, compared to their sizes, as illustrated in Figure 2. Because atoms and molecules have large separations, forces between them can be ignored, except when they collide with each other during collisions. The motion of atoms and molecules (at temperatures well above the boiling temperature) is fast, such that the gas occupies all of the accessible volume and the expansion of gases is rapid. In contrast, in liquids and solids, atoms and molecules are closer together and are quite sensitive to the forces between them.
