Questions: One sample of gas is at 0°C, while another is at 100°C. They are combined and end up at 50°C. Select the best description of what is happening. A Heat flows from the cooler sample to the warmer sample until the samples are the same temperature B Heat flows from the warmer sample to the cooler sample until the samples are the same temperature No heat flow occurs because the individual particles have the same kinetic energy as before, only the average is different

Solution

Solution Steps

Step 1: Analyze the Initial and Final Temperatures

We have two gas samples, one at 0°C and another at 100°C. When they are combined, the final temperature becomes 50°C. This indicates a temperature change in both samples.

Step 2: Determine the Direction of Heat Flow

Heat always flows from a hotter object to a colder object. In this case, heat flows from the 100°C sample to the 0°C sample.

Step 3: Describe the Process

Heat flows from the warmer sample (100°C) to the cooler sample (0°C). This transfer continues until thermal equilibrium is reached, resulting in a final temperature of 50°C for the combined sample.
