Hydrogen bonds keep the DNA bases paired together and maintain their structure. 4. A hydrogen bond is a true chemical bond. 5. Hydrogen attached to carbon cannot participate in hydrogen bonding when the carbon atom is bound to electronegative atoms. CHCI3 6. The change of phase from solid to gas is called Sublimation. _7. The motion/speed of the particles increases as the temperature of the particle decreases. 8. A change of phase from liquid to gas is called Transpiration. 9. Energy is either absorbed or released during a phase change 10. Cooling a gas may change the state to a liquid due to a change in measure. 11.
