What statement describes the phase change that occurs when dry ice is place in an open container at room temperature?
The dry ice sublimes directly from a solid to a gas without going through a liquid phase change. This process is known as sublimation.
Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature?
The dry ice will sublimate, which means it will change from a solid directly to a gas without passing through the liquid state. This process occurs due to the low temperature of dry ice (-78.5°C) compared to room temperature, causing it to transition directly to carbon dioxide gas.
If equal amounts of heat are added to two containers of water and the resultant temperature change of the water in one container is twice that of the wa ter in the other container then what can you sa?
The specific heat capacity of the water in the container with the larger temperature change is lower than that of the water in the other container. This means that the water with the larger temperature change requires less energy to heat up.
When wood is burned in a closed container its mass does not change is that observation or law?
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
Does gas have a definite volume and can change volume?
does gas take the shape of it's container and can change volume

Which statement describes the rate of change of the following function?
Which statement describes the rate of change of the following function?f(x) = -6x - 9

What statement best describes temperature variations?
Temperature variations refer to changes in temperature over a period of time. These variations can occur on a daily, seasonal, or long-term basis due to factors such as weather patterns, climate change, and geographic location. Understanding temperature variations is important for predicting weather patterns and assessing the impact of climate change.
Would the volume of oxygen change if it were moved into a larger container?
It does not because change only occurs when temperature is involved.
What is the effect of a decrease in volume of a sealed container of gas with no change in temperature?
A decrease in volume of a sealed container of gas with no change in temperature leads to an increase in pressure according to Boyle's Law. This is because the gas molecules are confined to a smaller space, resulting in more frequent collisions with the container walls.
What describes the phase change that occurs when dry ice is placed in an open container at room temperature?
When dry ice (solid carbon dioxide) is placed in an open container at room temperature, it undergoes sublimation, meaning it changes directly from a solid to a gas without passing through the liquid phase. This process results in the dry ice gradually turning into carbon dioxide gas and dissipating into the surrounding environment.
Why use LMTD and not mean temperature difference?
Because the temperature change that occurs across the heat exchanger from the entrance to the exit is not linear, and a logarithmic function best describes this temperature change.
What describes how temperature and pressure change with depth below Earth's surface?
Both temperature and pressure increase with depth.
When wood is burned in a closed container its mass does not change is that observation or law?
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
