1. Ah, 67 K in Celsius? That's like being stuck in an ice cube at -206.15 degrees Celsius! Brrr!

2. 458.9 Celsius in K? That's hotter than a fire-breathing dragon at 732.05 Kelvin!

3. Heat is closely related to thermal energy, like a never-ending toast party in your hot cocoa.

4. A low efficiency score reveals that a home has lots of unwanted and incidental heat transfer. It's like your home is playing hide-and-seek with heat, but it keeps finding its way in.

5. The best example of heat is when wood burns and releases 57 J of energy. It's like the wood is doing a fiery dance and saying, "Ta-da! Here's some heat for ya!"

6. Heat transfer by conduction is like stepping on hot sand with bare feet. Ouch! It's like an evil dessert, trying to fry your soles.

1. To convert 67 K to Celsius, you can use the formula: Celsius = Kelvin - 273.15. So, 67 K - 273.15 = -206.15 °C.

2. To convert 458.9 Celsius to Kelvin, you can use the formula: Kelvin = Celsius + 273.15. So, 458.9 °C + 273.15 = 732.05 K.
3. Heat is closely related to thermal energy (b).
4. A low efficiency score reveals that the home has a lot of unwanted and incidental heat transfer (d).
5. Wood burning releasing 57 J of energy best represents heat (b).
6. The fact that the hot sand is very painful to step on with bare feet best shows the transfer of heat by conduction (a).

To convert Kelvin (K) to Celsius (C), you need to subtract 273.15 from the temperature in K. For example, to convert 67 K to Celsius, you subtract 273.15 from 67 K, giving you -206.15 °C.

To convert Celsius (C) to Kelvin (K), you need to add 273.15 to the temperature in Celsius. For example, to convert 458.9 °C to Kelvin, you add 273.15 to 458.9 °C, giving you 732.05 K.

In question 3, the term "heat" is most closely related to thermal energy. Heat refers to the transfer of thermal energy between objects or systems.

In question 4, a low efficiency score for heat transfer in a home suggests that there is a lot of unwanted and incidental heat transfer. This means that the home is not effectively retaining or utilizing heat.

In question 5, the best example that represents heat is option b. Wood burning releasing 57 J of energy is an example of heat being generated or released as a result of a chemical reaction.

In question 6, the best example that demonstrates the transfer of heat by conduction is option a. The statement about hot sand being painful to step on with bare feet suggests the transfer of heat from the sand to the feet through direct contact (conduction).
