P3 Particle Model Of Matter

Question 1

<p>What does the Atom look like?</p>

Answer 1

Question 2

<p>What is the Charge and Relative massof a Proton?</p>

Answer 2

<p>The charge of a Proton is +1</p>

<p>The relative mass of a Proton is 1</p>

Question 3

<p>What is the Charge and Relative massof a Neutron?</p>

Answer 3

<p>The charge of a Neutron is 0</p>

<p>The Relative mass of a Neutron is 1</p>

Question 4

<p>What is the charge andrelative mass of an Electron?</p>

Answer 4

<p>The charge of an electron is -1</p>

<p>The relative mass of an Electron is 1/1840</p>

Question 5

<p>What is the equation to calculate Density?</p>

Answer 5

<ul>
<li>ρ=m/V</li>
<li>Density(kg/m³)= mass (kg) ÷ Volume (m³)</li>
</ul>

Question 6

<p>What is<strong>Upthrust</strong>?</p>

Answer 6

<p>Upthrust is the force that keeps an object in a liquid or gas buoyent as the density ofthe object is lower than the density of the fluid</p>

Question 7

<p>What is<strong>The Law of Displacement</strong>?</p>

Answer 7

<p>The Law of Displacement says that an object completely submerged in a fluid (like water) will replace an amount of fluid equal to its own volume</p>

Question 8

<p>What is the <b>Conservation of Mass</b>?</p>

Answer 8

<p>The Conservation of mass states that when a substance changes state, its mass will remain the same</p>

Question 9

<p>What are examples of changing state?</p>

Answer 9

<ul>
<li>Condensation</li>
<li>Melting</li>
<li>Boiling</li>
<li>Solidifying/Freezing</li>
<li>Sublimation</li>
<li>Deposition</li>
</ul>

Question 10

<p>What is another term for melting point?</p>

Answer 10

<p>Fusion temperature</p>

Question 11

<p>What is another term for Boiling point?</p>

Answer 11

<p><strong>Vaporisation Temperature</strong></p>

Question 12

<p>How do you calculate the change in thermal energy?</p>

Answer 12

<p>ΔE=m×c×Δθ</p>

<p>Change in Energy = mass× Specific Heat Capacity× Change in Temperature</p>

Question 13

<p>What is <strong>Specific Heat Capacity</strong>?</p>

Answer 13

<p>The <strong>specific heat capacity </strong>of a substance is the amount of energy needed to increase the temperature of 1 kg of that substance by 1°C</p>

Question 14

<p>What is<strong>Latent Heat</strong>?</p>

Answer 14

<p>Latent heat is the energy that is transferred to a substance without the substance's temperature changing. This happens when a substance is changing State</p>

Question 15

<p>How do you calculate<strong>Specific Latent Heat</strong>?</p>

Answer 15

<p>L = E ÷ m</p>

<p>Specific Heat Capacity = Energy Transferred ÷ Mass</p>
