What physical property of liquids and solids causes the speed of sound in them to be to be so much greater than the speed of sound in air?
Because of their density, sound waves in the air travel more quickly through the solid and liquid mediums. The energy of a compression wave (such as a sound wave) must pass from atom to atom, which makes the more tightly packed atoms of non-gascious mediums more efficient in transferring sound.
What else can I help you with?
Is heat produced when two liquids are mixed a physical change?
No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.
Liquids from spherical drops because of this property?
Surface tension is the property that causes liquids to form spherical drops. This is due to the molecules at the surface of the liquid being more attracted to each other than to the surrounding air, causing them to minimize surface area and form a sphere.
What physical property of carbon dioxide allows gas to be collected?
The physical property of carbon dioxide that allows gas to be collected is its higher density compared to air. This causes carbon dioxide to sink and accumulate in a container when released, allowing for easy collection.
What physical property causes earth's core to be made up of heavier elements including metals such as iron and earth's crust to be made of lighter elements such as silicon?
Density.
What causes particles to settle the most?
Greater density causes particles to settle faster.
What property of liquids causes water droplets to form?
Because the water molecules attract each other more strongly than they are attracted to the substances around them. (Cohesion is greater than adhesion).
A sentence for the word electric charge?
an electrical charge is a physical property of matter which causes it to experience a force when near other electrically charged matter

What is charge?
Charge is a physical property that causes matter to experience a force within an electromagnetic field.
What liquids form spherical drops because of this property?
Liquids with high surface tension, such as water, form spherical drops due to this property. Surface tension is the cohesive force that causes molecules at the surface of a liquid to be drawn inward, creating a spherical shape to minimize surface area.
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
What property of matter causes an object to have inertia of rest?
The property of matter that causes an object to have inertia of rest is its mass. Mass is a measure of the amount of matter in an object and determines how difficult it is to change the object's state of rest or motion. Objects with more mass have greater inertia of rest.
Which property of water causes a curved surface?
Adhesion is the property of water causes the curved surface
What physical property of carbon dioxide allows gas to be collected?
The physical property of carbon dioxide that allows gas to be collected is its higher density compared to air. This causes carbon dioxide to sink and accumulate in a container when released, allowing for easy collection.
Is TNT explosion a chemical property?
No, an explosion is a physical property that results from the release of stored energy. The chemical property of TNT is its ability to undergo rapid decomposition in a highly exothermic reaction, leading to the release of gas and heat that causes the explosion.
What expands when heated?
Most substances expand when heated because the heat causes the particles to move more rapidly, increasing the space between them and causing them to take up more volume. This expansion is known as thermal expansion and is a common physical property exhibited by solids, liquids, and gases when exposed to heat.
