Test: Time and Temperature - Class 4 MCQ

Using the formula F = (C × \frac{9}{5}) + 32, converting 25°C gives 77°F. Understanding temperature conversions is vital for cooking, weather forecasting, and scientific research.

60 seconds is equivalent to 1 minute. This basic conversion is fundamental for understanding time measurement and is used in everyday situations.

The boiling point of water is 212°F. Knowing the boiling and freezing points is essential in cooking and scientific contexts, providing a basis for various thermal processes.

To convert hours to minutes, you multiply by 60. This simple multiplication is crucial for many daily tasks, such as scheduling and time management.

Elapsed time is calculated by counting forward or backward between two times. This method helps in understanding durations of events and planning activities effectively.

The second hand on a clock indicates seconds. It completes a full circle in one minute, allowing for precise measurement of time, particularly useful in timing events or measuring intervals.

There are 720 seconds in 12 minutes, calculated by multiplying 12 by 60. This conversion is frequently used in timing events and activities.

The freezing point of water is 0°C. This temperature is critical for various scientific studies and practical applications, including cooking and weather predictions.

14:00 in 24-hour format is equivalent to 2:00 p.m. in 12-hour format. This conversion is important for clarity in everyday communication.

Dividing 428 by 24 gives 17 days with a remainder of 20 hours. This method of conversion is essential in fields such as project management, where durations need to be accurately calculated.

To convert 3:30 p.m. to 24-hour format, you add 12 to the hour, resulting in 15:30. This conversion is crucial for contexts like transportation schedules, where the 24-hour format is often used.

Adding the time yields 5 hours, 51 minutes, and 5 seconds. This process involves careful addition and carrying over when necessary, which is a key skill in time management.

To convert 150 minutes, divide by 60 to get 2 hours with a remainder of 30 minutes, thus 2 hours and 30 minutes. This conversion is useful for time management in daily activities.

There are 7,200 minutes in 5 days, calculated by multiplying 5 days by 1,440 minutes (24 hours × 60 minutes). This calculation is important in planning and scheduling.

The formula for converting Celsius to Fahrenheit is F = (C × 1.8) + 32. Mastering this formula is essential for understanding temperature in different contexts, particularly in science and cooking.
