Which symbol is commonly used to represent thermal energy in chemistry?

• A. q
• B. T
• C. E
• D. H

Answer: (A)

Verified step by step guidance

1. Understand that thermal energy in chemistry is often related to heat transfer during a process.
2. Recall that the symbol commonly used to represent heat or thermal energy in thermodynamics and chemistry is 'q'.
3. Recognize that 'T' typically represents temperature, 'E' can represent energy in general but is not specific to thermal energy, and 'H' represents enthalpy.
4. Therefore, the symbol 'q' is the standard notation for thermal energy or heat exchanged in a system.
5. Conclude that among the given options, 'q' is the correct symbol to represent thermal energy.
