Answer: Thermal energy is the kinetic energy of particles and heat is the term used to describe how this energy may flow to other systems, such as in a radiator.
Explanation: Molecules have a level of kinetic energy that can be measured by temperature. Higher temperatures result in more rapid and frequent collisons of particles in motion. Heat is the term used to measure the quantity of vibration energy in a given system. The SI unit for heat energy is the Joule. The water molecules in a pot of boiling water have a kinetic energy sufficient for them to break away from other water molecules and become gaseous (boiling point). The heat energy in 1 liter of water at 95C can be calculated in terms of Joules/liter, based on the specific heat of water (e.g., in units of J/gC). This heat can flow to other systems. A home boiler heater unit heats water tha can be pumped around the house ehre it will flow from radiators into thje surrounding air.

You should clean up after every investigation because if you leave a mess, maybe another detective will come in and get lost because of the mess you left.
Answer:
Chemical
Explanation:
The change was chemical, because it can no longer be returned to the original form. You cannot get back the bubbles or fizz from the air.
Answer:
9.62 × 10² J
Explanation:
In this problem, we need to convert 230 calories to joules. For this, we must know the conversion from calories to joules.
1 Calorie = 4.184 Joules
To find Joules in 230 calories, multiply 4.184 by 23. So,
230 Calorie = (230 × 4.184) Joules
= 962.32 Joules
or
230 Calories = 9.62 × 10² J
So, the correct option is (A).
