How does the strength of the forces that hold the basic particles of a substance together relate to the temperature at which the substance changes
state?
OA. Weaker forces between particles means the substance boils at a
higher temperature.
OB. Stronger forces between particles means the substance boils at a
OC. Stronger forces between particles means the substance melts at a
OD. Stronger forces between particles means the substance boils at a
higher temperature.

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.

The equation picture below shows which type of nuclear reaction u 235 + n x e 134 + sr 100 + 2n
