Heat and temperature are words we often use in everyday talks, but they mean different things in science. Knowing the difference is important, especially when we look at real-life situations.
Heat: Heat is the energy that moves from one thing to another because of a temperature difference. It goes from something hot to something cool until both have the same temperature. We measure heat in Joules (J).
Temperature: Temperature tells us how hot or cold something is. It measures the average energy of the tiny particles in a substance. We measure temperature in degrees Celsius (°C), Kelvin (K), or Fahrenheit (°F).
When you cook on a stove, the heat from the burner warms up the pan. For example, the pan might reach 200 °C while the food, like an egg, starts at 20 °C. The heat moves from the pan to the egg until they are both the same temperature. This shows how heat and temperature work together.
Imagine pouring ice cubes into a glass of water. The water might start at 30 °C, while the ice is at 0 °C. Heat moves from the warmer water into the colder ice. This makes the water cooler and the ice melts. However, the ice stays at 0 °C until it has completely melted. This example shows that heat can change the temperature of things in different ways.
A thermos flask keeps your drink hot or cold by stopping heat from moving. Inside the flask, your drink might be 85 °C, while the room is at 20 °C. The heat from your hot drink tries to escape into the cooler room, but the thermos keeps this heat inside. This means your drink stays warmer for a longer time. Here, you can see how temperature and heat transfer are different.
Think about a cup of coffee sitting on a table. It might start at 90 °C, while the room is 22 °C. The coffee has more thermal energy (heat) because it’s hotter than the air around it. Over time, heat from the coffee moves to the air, making the coffee cooler. This shows that even though the coffee's temperature goes down, heat is still leaving it.
These examples help us understand that temperature is about how much thermal energy something has, while heat is the energy that moves because of differences in temperature. Knowing this difference can help us with everyday things, like cooking and keeping drinks at the right temperature!
