<ul>
	<li>Specific heat capacity is like a &quot;thermal fingerprint&quot; for a substance. It tells you how much energy is needed to raise the temperature of 1 kg of that substance by 1K.</li>
</ul>

🔥 Fun Fact: Pour 1000J of energy into 1 kg of water, it gets warmer by roughly \(\frac12\) K. Do the same with 2 kg of copper, and it heats up by 1.3K. Imagine the water as a lazy sunbather that likes to absorb energy slowly, while the copper is that overexcited kid that heats up quickly!

c = m &times; &Delta;TQ​ Where

<ul>
	<li>c = Specific heat capacity (Units -&nbsp;J/kg.K)</li>
	<li>Q = Energy transferred</li>
	<li>m = Mass of the substance</li>
	<li>&Delta;T = Temperature change</li>
</ul>

<ul>
	<li>Water&rsquo;s Specific Heat: cwater​ = 4000 J/kg.K</li>
	<li>Copper&rsquo;s Specific Heat: ccopper​ = 380 J/kg.K</li>
</ul>

Did You Know?

<ul>
	<li>Water, being the drama queen it is, has one of the highest specific heat capacities around. Thanks to something fancy called &quot;hydrogen bonding&quot;, where a hydrogen atom from one water molecule links with an oxygen atom from another molecule.</li>
</ul>

<ul>
	<li>High specific heat of water = life-saver for animals! It allows animals to maintain a stable temperature.</li>
	<li>Large bodies of water in the atmosphere help stabilize our climate since they need heaps of energy to experience significant temperature changes.</li>
</ul>

<ul>
	<li>For a Solid (Like Aluminum)
	<ul>
		<li>Heat it up using a resistance wire (like the one in toasters).</li>
	</ul>
	</li>
	<li>Use the formula: c = \(\frac {vIt}{mΔθ}\)</li>
	<li>Side note: Make sure to consider energy losses to the surroundings. Maybe throw in some insulation!</li>
	<li>For a Liquid
	<ul>
		<li>Use the &quot;method of mixtures&quot;. It&#39;s like mixing cold milk with hot coffee and figuring out the final temperature.</li>
	</ul>
	</li>
	<li>Key equation: mm &times; cm &times; (100 &ndash; T final​) = mw &times; cw &times; (T final​&ndash;Tinitial​)</li>
	<li>Pro tip: Start with the initial water temperature being as much below room temperature as it ends above. It helps account for energy losses.</li>
	<li>Efficiency of a Kettle
	<ul>
		<li>Heat some water and measure the energy used and the temperature change.</li>
	</ul>
	</li>
	<li>Use the formula with the given specific heat for water: c = 4200J/kg.K.
	<ul>
		<li>You can also try this with a microwave! But remember, microwaves work differently than traditional heating methods.</li>
	</ul>
	</li>
</ul>

Steam from heated water can turn turbines, which generate electricity! That&#39;s how many power plants work. Imagine the power of steam pushing giant blades, just like wind turns a windmill.

Specific heat capacity is a super cool way (pun intended!) of understanding how different substances respond to energy. Whether it&rsquo;s the water in our oceans, the metal in our pots, or the steam in our engines, understanding this concept can unlock so many wonders of our world! 🌟
