A radio opaque substance is something that resists the passage of X-Rays, or other radiation. It is often injected into the heart for a coronary angiogram, into the brain for a cerebral angiogram, or into the cerebralspinal fluid for a myelogram. It makes things stand out on an X-Ray or fluoroscope, making it easier to see internal structures and conditions. It can also be injected systemically, to enhance the constrast of an ordinary X-Ray or CT scan.

Is the following sentence True or false microwave are the radio waves with the shortest wavelengths and highest frequencies?
True. Microwaves have shorter wavelengths and higher frequencies compared to radio waves, falling between infrared radiation and radio waves on the electromagnetic spectrum.
Is the following true or false temperature is a measure of how hot or cold the substance is?
False. It is a measure of how much enegry a substance has.
Is the following sentence true or false microwaves are the radio waves with the shortest wavelengths and highest frequencies?
True. Microwaves have shorter wavelengths and higher frequencies compared to radio waves, making them suitable for various applications such as cooking, communication, and radar.
Is the following sentence true or false the faster the particles of a substance are moving the more energy they have?
True. The kinetic energy of particles is directly proportional to their speed. As the particles move faster, their energy increases.

True or False- Energy is transferred as heat from a substance at high temperature to a substance at low temperature?
True. Heat is transferred from a substance at high temperature to a substance at low temperature to reach thermal equilibrium.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
