Answer:
Q = 2260.44 j
Explanation:
Given data:
Mass of ice = 18 g
Initial temperature = -10 °C
Final temperature = 20°C
Heat absorbed by ice = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = Final temperature - initial temperature
ΔT = 20°C - (-10°C)
ΔT = 30°C
Specific heat of water = 2.00 j/g.°C
Q = 18 g × 4.186 j/g.°C × 30°C
Q = 2260.44 j
Answer:
Hey there!
The volume of the box would be 45(7)(15), or 4725 cm^3.
The density of any object is the mass divided by volume. Thus, the density of the water would be 14/2, or 7 g/cm^3.
Let me know if this helps :)
Both chloro and methyl groups axial
More stable
Higher concentration
According to the report of US Environmental Protection
Agency, majority of large dose radiation exposure comes from natural background
radiation sources particularly the radioactive gases radon and thoron. This two
gases form when naturally occurring elements decay. However in the case of
man-made sources, the largest dose comes from medical x-rays.
