and take multiple measurements tn average them out.

make ur object totally dry before you start next measurement.

sorry if wrong

Explanation:

Precise volumes must always be measured at constant temperature because, due to thermal expansion, changes in temperature are followed by changes in volume. For example water at 10 °C has much smaller volume than at 80 °C. Volumetric vessels are usually calibrated for 20 °C (25 °C in the USA).

i think that the best answer would be c.

tell me if im wrong : )

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
