Transcribed Image Text:A sample of **solid silicon** is heated with an electrical coil. If **133 Joules** of energy are added to a **11.0 gram** sample initially at **20.6°C**, what is the final temperature of the **silicon**?
Answer: ____ °C.
![**Problem Statement:**
A sample of **gaseous hydrogen** is heated with an electrical coil. If **2050 Joules** of energy are added to a **10.1 gram** sample and the final temperature is **35.8°C**, what is the initial temperature of the **hydrogen**?
**Answer:** _____ °C.
---
**Explanation:**
This question involves using the formula related to heat transfer in substances:
\[
q = m \cdot c \cdot \Delta T
\]
Where:
- \( q \) is the heat added (2050 Joules),
- \( m \) is the mass of the substance (10.1 grams),
- \( c \) is the specific heat capacity of gaseous hydrogen (we can assume it’s typically \( 14.3 \, \text{J/g°C} \) for hydrogen),
- \( \Delta T \) is the change in temperature (final temperature minus initial temperature).
The goal is to solve for the initial temperature using the given information.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4295bf62-da14-49f1-b3bf-6e678bc68de3%2F59c5989b-5b35-4a59-b9c6-71c9b1b33c51%2Fk8d3zsg_processed.jpeg&w=3840&q=75)
