What else can I help you with?
True or false the freezing point of water can be lowered with the addition of salt?
True - adding salt to water lowers its freezing point. This occurs because the presence of salt disrupts the formation of ice crystals, requiring lower temperatures for the water to freeze.
Water can change from one state to one state to another true or false?
True. Water can change from a solid state (ice) to a liquid state (water), and from a liquid state to a gaseous state (steam) depending on the temperature and pressure conditions.
You can re-calibrate a thermometer using either ice point or boiling water methods true or false?
True. A thermometer can be re-calibrated using the ice point method by immersing it in a mixture of ice and water at 0°C, or the boiling water method by placing it in boiling water at 100°C at standard atmospheric pressure. Both methods provide fixed reference points for accurate calibration.
What are three substances that have a lower density then water?
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
True or false if ice did not float the earths entire climate would be marked different?
True. If ice did not float, it would sink instead, leading to ice forming at the bottom of bodies of water. This would disrupt the cycling of nutrients and the temperature regulation of aquatic environments, impacting the earth's climate and ecosystems significantly.
True or false dry ice is icefrom which all water has been removed?
False - dry ice does not contain water; it is frozen carbon dioxide
Do clouds formed when water vapor in the air Conference to form the liquid water or ice crystals true or false?
Yes water drops or ice depending on the temperature. But they do not "Conference" to do this, it is delegates that do that. Thus the answer is both true and false.
True or false 10 g of ice contains less heat energy than 10 g of water?
True
If cold water sinks why is ice on top of pond?
Ice is lighter than the water it displaces .
Is the source of all clouds and precipitation is water vapor True or False?
True. Clouds and precipitation are formed when water vapor in the atmosphere condenses into liquid water droplets or ice crystals.
Is this true or false water is more dense in its solid form than it is in its liquid phase?
Technically it's neither true nor false without additional information (we would need to know the temperature and pressure). However, for "ordinary" conditions that you might find on or near the surface of the Earth, ice (solid water) is less dense than water (liquid water).
True or false the freezing point of water can be lowered with the addition of salt?
True - adding salt to water lowers its freezing point. This occurs because the presence of salt disrupts the formation of ice crystals, requiring lower temperatures for the water to freeze.
What is the freezing point of Robitussin AC?
it freezes when ice sinks in water
Is it true or false that frozen water melts?
True. Frozen water, or ice, melts when it is exposed to temperatures above its freezing point (0°C or 32°F). This causes its molecular structure to break down, transitioning it back into a liquid state known as water.
True or false seaweed is used to thicken ice-cream?
yes it is True
Why does ice cubes float in your drink but crushed ice sinks and blocks your straw?
Because ice is lighter than water
Is ice sinks in water?
No, because ice has a density of .92g/ml allowing it to float over on water's 1g/ml density.
