What else can I help you with?
A scale reports a 15-pound weight as weighing 12.375 pounds?
The scale is incorrectly calibrated, causing it to underestimate the weight by 2.625 pounds. This discrepancy may be due to various factors such as wear and tear, improper calibration, or damage to the scale's internal components. Recalibration or repairs may be necessary to ensure accurate weight measurements in the future.
Why is it necessary to tare a balance before weighing an object?
Taring a balance ensures that the weight of the container holding the object is not included in the final measurement, giving an accurate reading of the object's weight alone. This helps in obtaining precise and reliable measurements of the object being weighed.
Why do you have to weigh the empty container first before placing the substance to be weighed?
Weighing the empty container first allows you to subtract its weight from the total weight of the container and substance together to determine the precise weight of the substance being measured. This ensures an accurate measurement of the substance's weight without the added weight of the container affecting the result.
Why do you weigh by difference?
Weighing by difference is a technique used to calculate the weight of a substance by measuring the weight of the container before and after adding the substance. This method helps to eliminate errors caused by the container's weight, ensuring more accurate measurements of the substance.
What is the function of weighing scale?
Weighing scales are used to measure the weight of an object or a person. They are commonly used in various settings such as kitchens, laboratories, and retail stores to provide accurate weight measurements for different purposes.
Can you measure your weight?
Yes, by standing on accurate weighing scales.
What is true if a digital scale reports a 10kg weight as weighing 8.975 kg?
The scale is precise but not accurate. (APEX)
Is the crystal weighed in or out of the bag?
The crystal is typically weighed out of the bag to ensure accurate measurement and to avoid any interference from the bag's weight. Weighing it separately allows for a precise determination of the crystal's mass. However, if the bag is lightweight and the weight needs to be included, it may be weighed together, but this is less common in precise measurements.
What is the meaning of resolution in weighing scales?
Resolution in weighing scales refers to the smallest increment or change in weight that the scale can detect and display. It indicates the precision of the scale; for example, a scale with a resolution of 0.01 grams can measure weight changes as small as that amount. Higher resolution allows for more accurate and detailed measurements, making it essential for applications requiring precise weight assessment.

Why must be crucible be cold before weighing?
A crucible must be cold before weighing to ensure accurate measurements. If a hot crucible is weighed, it can cause air currents and thermal convection that affect the scale's reading, leading to an inaccurate measurement of the crucible's weight. Additionally, weighing a hot crucible can risk damaging the balance or scale. Lastly, cooling the crucible allows for any residual materials to settle, providing a more precise weight.
What does weighing resolution of balance specify?
The weighing resolution of a balance specifies the smallest increment of weight that the balance can reliably measure and display. It indicates the precision of the balance, determining how finely it can detect changes in weight. A higher resolution means the balance can differentiate smaller weight differences, which is crucial for applications requiring accurate measurements. This specification is essential for ensuring the balance meets the needs of specific tasks, such as in scientific research or quality control.
