Question
The more massive a radioactive decay panicle is, the higher its ionizing power and lower its penetrating power. Which radioactive decay particle has the highest ionizing power and lowest penetrating power? positron beta particle gamma ray alpha particle The heating curve for aluminum is shown here. The melting point for aluminum is 658 degree C. Which relationship is used to determine the of heat added the section of the curve indicated by the arrow? q = m times C_solid times (758 - 458 degree C) q = m times Delta H_vap q = m times C_liquid times (758 - 658 degree C) q = m times Delta H_fus One version of the Clausius - Clapeyron equation is In P = - Delta H_wap/RT + In beta. The slope of a straight-line plot of can be used to determine the enthalpy of vaporization. P_vap v.s T In P_vap vs. T P_vap vs. 1/T In P vap vs. 1/TExplanation / Answer
44) alpha particles are doubly charged helium ions having high ionising power and least penetrating power, thus can be checke d by even a small sheet of paper.
beta particle- checked by few mm of metal such as Al
gama particle- very high penetrating power
