Textbook Question
An air bubble at the bottom of a lake 32.0 m deep has a volume of 1.00 cm³ . If the temperature at the bottom is 5.5°C and at the top 18.5°C, what is the radius of the bubble just before it reaches the surface?

Why does a coastal area experience less variation in temperature compared to a non-coastal area?
A
The presence of mountains near the coast stabilizes the temperature.
B
Coastal areas receive more sunlight throughout the year.
C
The ocean absorbs and releases heat more slowly than land.
D
Coastal areas have higher humidity, which prevents temperature changes.
Verified step by step guidance1
Understand the concept of specific heat capacity: Water has a higher specific heat capacity than land, meaning it can absorb more heat without a significant change in temperature.
Consider the thermal properties of water: The ocean absorbs heat during the day and releases it slowly at night, moderating the temperature of coastal areas.
Analyze the effect of heat absorption and release: Since the ocean absorbs and releases heat more slowly, it prevents extreme temperature fluctuations in coastal areas.
Compare with non-coastal areas: Land heats up and cools down more quickly than water, leading to greater temperature variations in non-coastal areas.
Conclude with the impact on climate: The ocean's ability to moderate temperature results in a more stable climate for coastal regions compared to inland areas.
