How does heat affect a water droplet's state of matter
Olegator [25]

Answer:

Explanation:

A substance with a high specific heat, such as the water in Figure 9, heats up and cools down slowly because a much larger quantity of heat is required to cause its temperature to rise or fall by the same amount. Matter can change from one state to another when thermal energy is absorbed or released.

Describe two physical and two chemical changes involved in cooking. (4 points)
Ivenika [448]
Physical changes are when things get changed without altering chemical consistencies, which is melting solid butter into liquid one, or boiling water. Chemical changes are things such as caramelizing sugar when making sweets, or when carbon dioxide is created and released when baking bread.

2. What is the mass of a car with a momentum of 10,000.00 kgm/s, traveling at 15.0 m/s?
Svetradugi [14.3K]

Answer:

666.67 kg is the mass of a car.

Explanation:

Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.

Momentum(P)=Mass(m)\times Velocity(v)

Mass of the car = m =?

Velocity of the car = v = 15.0 m/s

Momentum of the car = P = 10,000.00 kgm/s

m=\frac{P}{v}

m=\frac{ 10,000.00 kgm/s}{15.0 m/s}=666.67 kg

666.67 kg is the mass of a car.
