Physical Science Chapter 6? Quiz & Assessment
The lowest temperatuer in nature is... 0 degrees Celsius. -273 degrees Celsius. 4 K.
-273 degrees Celsius.
Temperature is different from heat because... temperature is measured in degrees, and heat is measured in units of energy. temperature is a measure of translational kinetic energy per molecule, and heat is energy that moves from high to low temperature. temperature is a ration of energy per molecule, and heat is energy in transit. All of these.
All of these
The ocean level rises when global temperature rises, due to... melting of ice caps at the poles. thermal expansion of water. Both of these. Neither of these.
Both of these
The first law of thermodynamics is a restatement of what general principle? Pascal's principle. Joule's principle. Rumford's principle. Energy conservation.
Energy conservation
When we discuss the measure of disorder in a system, we are discussing what concept? Thermodynamics. Initial energy. Efficiency. Entropy
Entropy
The temperature at the bottom of Lake Tahoe in the Sierra Nevada Mountains of California is 4 degress C year-round. In which country is water at the bottom of lakes normally higher than this? Russia. Great Britain. Singapore. New Zealand.
Singapore
Which physics concept listed below has most to do with world climate? Temperature. Heat. Expansion. Specific heat capacity.
Specific heat capacity
When water at 4 degrees C is warmed, it expands. When water at 4 degrees C is cooled, it... also expands. contracts. Both expands and contracts with no net change.
also expands
The second law of thermodynamics deals with... certainties. probabilities. Neither of these answers.
certainties
When an iron ring is heated, the hole in the ring becomes.. smaller. larger. a bit smaller and larger with the result that no net change in hole size occurs.
larger
A substance that heats up relatively quick is said to have a... high specific heat capacity. low specific heat capacity. either high or low-conductivity is more important.
low specific heat capacity
