Question

1. record any two of the following temperatures in your lab environment. in each case, allow the end bulb of the celsius thermometer to remain in or on the sample for one minute. room temperature = ____ °c surface of your skin = __ °c cold tap water in a 50 ml beaker = __ °c hot tap water in a 50 ml beaker = __ °c ice water = ____ °c

Explanation:

This is a practical lab task to measure temperatures. Since it's about recording observed temperatures, here are typical expected values (these are approximate and can vary based on actual conditions):

• Room temperature: Typically around 25 °C in a comfortable lab setting.
• Surface of your skin: Around 32 - 34 °C (average skin surface temperature).
• Cold tap water: Around 10 - 15 °C (varies by location and season).
• Hot tap water: Around 40 - 50 °C (depends on water heater settings).
• Ice water (with ice and water in equilibrium): Around 0 °C (melting point of ice).

For example, if we choose to record room temperature and ice water:

Answer:

Room temperature = $\boldsymbol{25}$ °C
Ice water = $\boldsymbol{0}$ °C

(Note: These are example values. Actual values should be measured in the lab environment as per the instructions.)
