When the temperature of ice is increased slightly. Does it undergo a net expansion or net contraction?
Net Contraction
What is the shrinking of a substance called?
Since expansion is the process of a substance's dimensions increasing, e.g., thermal expansion caused by a rise in temperature, the logical opposite would be contraction.
What is the advantage of having perforated walls amonth the vessel elementS?
To reduce pressure by giving room of expansion or contraction when temperature increases or reduces from the surrounding _
What is the breaking of rocks due to constant expansion an contraction called?
Weathering.
What is the breaking of rocks due constant expansion and contraction called?
Exfoliation.
Do you agree that expansion and contraction only cause problems?
No, we use expansion and contraction to tell temperature(thermometer).
Why do railway lines have gaps in them?
to allow for the thermal expansion or contraction
When the temperature of ice is increased slightly. Does it undergo a net expansion or net contraction?
Net Contraction
Why does temperature weather rocks?
Expansion & contraction. But that's tiny compared to the expansion of water into ice (which is also a function of temperature).
When the temperature of ice cold water is increased slightly does it undergo a net expansion or net contraction?
net contraction
When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
Two reason why Mercury is used in thermoters?
compatible expansion/contraction characteristics -- linear expansion and contraction for the normal temperature range; low freezing point of -38 degrees C
When the temperature of ice cold water is increased slightly dpoes it undergo a net expansion or net contraction?
Contraction for a few degrees Celsius.
Why are there joints in bridges?
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
What is temperature measured to?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)
What is measured using temperature?
Temperature is usually measured via expansion/contraction of a liquid (liquid thermometer), differences in expansion/contraction of two metals (bi-metallic strip thermometer), changes in electrical resistance (thermistor or thermocouple) or radiant energy (for example: a pyrometer)
How does law of expansion and contraction work in thermometers?
The material in the thermometer expands and contracts as temperature increases or reduces.
