When all molecular activity stops a substance is?
the temperature of −273.16°C (−459.69°F), the hypothetical point at which all molecular activity ceases.
Does water at 0 degrees Fahrenheit have molecular activity?
Water boils at 212 degrees Fahrenheit under standard conditions. Water at 0 degrees Fahrenheit has no heat energy or molecular activity.
When water at 212 Fahrenheit boils it is only absorbing latent heat?

Term What is heat? | Definition The reverse of cold, something that feels warm. Heat is a form of energy, often defined as energy transfer. |

Term True or False: When water boils at 212 deg F, it’s only absorbing latent heat. | Definition True |
What temperature does all molecular motion stop?
absolute zero
A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius.
What is the temperature at which all the molecular movement assumed to stop?
0 degrees Kelvin
All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius.
Which temperature does all molecular motion stop?
What temperature would it be if all the molecules stop moving?
At the physically impossible-to-reach temperature of zero kelvin, or minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius), atoms would stop moving. As such, nothing can be colder than absolute zero on the Kelvin scale.
What does water do at 212 degrees?
Above 212°F at standard pressure, liquid water is unstable. It will evaporate very rapidly from the surface. If the temperature is much above 212°F, the water will boil. That means that it won’t just evaporate from the surface but will form vapor bubbles, which then grow, inside the liquid itself.
Does water boil at 212 C?
It seems like one of those basic science facts: Water boils at 212 degrees Fahrenheit (100 degrees Celsius), right? Well, not always. It depends on where you’re doing the boiling. In fact, water will boil at about 202 degrees in Denver, due to the lower air pressure at such high elevations.
Does latent heat change with temperature?
latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Can latent heat be measured with a thermometer?
A thermometer cannot measure latent heat. The higher the room humidity, the greater the latent heat present. The total of sensible and latent heat is known as enthalpy.
What’s the lowest temperature at which molecular motion stops?
The temperature at which all molecular motion ceases is known as… See full answer below. Our experts can answer your tough homework and study questions. Absolute zero refers to the lowest temperature limit when all particle motion stops almost completely. Learn how scientists defined this concept through experiments.
Which is the absolute zero temperature on the Kelvin scale?
The temperature is called absolute zeroand is approximately -273.15 °C, or zero on the Kelvin scale. The Kelvin scale is named after the Belfast-born engineer and physicist William Thomson, 1st Baron Kelvin (1824-1907), who wrote of the need for an “absolute thermometric scale”.
How does temperature affect the motion of matter?
The colder a substance is, the less molecular motion that will be present within it. As an object changes temperature, its state of matter (i.e., solid, liquid, or gas) will also change, and there will be a large change in the molecular motion of a substance when it shifts from one state of matter to another.
Is the Kelvin the same as the degree Celsius?
Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or typeset as a degree. The kelvin is the primary unit of measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude.
