The experiment shows that energy exchanges between objects differs.
The experiment shows that energy exchanges between objects differs.

The experiment shows that collecting data is flawed.

Answer 1

The correct response is:

The experiment shows that replication of natural events is difficult.

This option highlights the challenges associated with conducting experiments in the physical sciences, where even controlled conditions can lead to variations in results due to numerous factors.

Answer 2

Which of the following would violate laboratory safety rules?(1 point)
Responses

wearing gloves when handling chemicals
wearing gloves when handling chemicals

tying long hair back when near an open flame

wearing goggles when lab materials are being used
wearing goggles when lab materials are being used

wearing open-toed shoes when chemicals are being used

Answer 3

The response that would violate laboratory safety rules is:

wearing open-toed shoes when chemicals are being used.

This option poses a safety risk, as open-toed shoes can expose the feet to spills and other hazards in the lab environment.

Answer 4
