What else can I help you with?
Is it true or false critical pressure is the pressure that will cause solid las to liquefy at the critical temperature?
False. Critical pressure is the pressure required to liquefy a substance at its critical temperature, but it does not refer to the pressure that will cause a solid to liquefy. At the critical temperature, a substance cannot exist as a liquid and vapor phase; therefore, the concept of solid melting into a liquid under critical pressure is not applicable.
Why aren't properties affected by changes in temperature and pressure?
Properties of a substance, like density or specific heat, aren't affected by changes in temperature and pressure because they are intrinsic characteristics that depend on the nature of the substance itself, regardless of external conditions. These properties are determined by the molecular structure and interactions within the substance, which remain constant despite changes in temperature or pressure.
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.
In a rigid container as the temperature of a gas decreases the pressure of the gas will decrease true or false?
False
Below the critical temperature no amount of pressure will cause a liquid to solidify true or false?
Well, according to the informotation provided in the above article. I have come to the conclusion that it is a falst AND a true statement. Because 784.353 oz divided by 72988.666 is the square root of a mamoths foot.
True or false the density of a substance is the same for all samples of substance?
False. The density of a substance can vary depending on factors such as temperature and pressure. Additionally, impurities in a sample can also affect its density.

True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
Is this true or false properties are not affected by changes in temperature and pressure?
false
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.
True or false temperature is a measure of how hot or cold a substance is?
How hot or cold a substance is the temperature, so a thermometer will measure it.
The pressure of a gas decreased with increasing temperature?
False
The amount of pressure in a gas is measured in pascals true or false?
True.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
Is volume is a measure of how much the particles of a substance decrease under pressure?
FALSE
In a rigid container as the temperature of a gas decreases the pressure of the gas will decrease true or false?
False
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.
Below the critical temperature no amount of pressure will cause a liquid to solidify true or false?
