Multiple choice

What is the relationship between Celsius and Kelvin temperature scales?

  1. K = °C + 273.15

  2. K = °C - 273.15

  3. K = °C / 273.15
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The relationship between Celsius and Kelvin temperature scales is K = °C + 273.15. This means that to convert a temperature from Celsius to Kelvin, you add 273.15 to the Celsius value.

Multiple choice

What is the relationship between Fahrenheit and Kelvin temperature scales?

  1. K = (°F - 32) * 5/9

  2. K = (°F + 32) * 5/9

  3. K = (°F - 32) * 9/5
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

The relationship between Fahrenheit and Kelvin temperature scales is K = (°F + 459.67) * 5/9. This means that to convert a temperature from Fahrenheit to Kelvin, you add 459.67 to the Fahrenheit value and then multiply by 5/9.

Multiple choice

What is the recommended temperature for washing cotton fabrics?

  1. Hot (60-90°C)

  2. Warm (40-60°C)

  3. Cold (30°C or below)

  4. Any temperature is acceptable
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cotton fabrics are generally safe to wash in warm water, but hot water can cause them to shrink or fade.

Multiple choice

What is the recommended temperature for ironing cotton fabrics?

  1. Low (110-150°C)

  2. Medium (150-175°C)

  3. High (175-200°C)

  4. Any temperature is acceptable
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cotton fabrics can generally be ironed at a medium temperature, but high temperatures can damage the fibers.

Multiple choice

Which of the following is the most suitable temperature range for storing bread?

  1. Room temperature (20-25°C)

  2. Refrigerator temperature (4-5°C)

  3. Freezer temperature (-18°C or below)

  4. Any temperature is acceptable
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bread is best stored at room temperature, typically between 20-25°C, to maintain its freshness and flavor. Refrigeration can cause the bread to dry out and become stale more quickly, while freezing can alter its texture and taste.

Multiple choice

What is the recommended temperature for storing frozen meals in a freezer?

  1. 0°F (-18°C)

  2. 10°F (-12°C)

  3. 20°F (-7°C)

  4. 30°F (-1°C)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Frozen meals should be stored at 0°F (-18°C) or below to maintain their quality and prevent bacterial growth.

Multiple choice
